Recognizing when a guy has feelings for you isn't all that difficult. You can easily figure out if he's interested in you by paying attention to his body language and the frequency of eye contact he makes with you!
Steps
Observe his actions

Notice if he cares about you. Does he bring you coffee? Does he offer to drive you home? Unless he's a model citizen to an extreme, chances are, he's simply acting on his feelings. He definitely likes you and wants to receive affection from you, not just a "thank you" for the kind things he's doing for you.

Observe if he's making excuses to stay close to you. Does he offer to help with anything, like fixing things around the house or shoveling snow off the driveway? Has he cooked a meal for you because you had a tough day? If he's always near you, finding multiple ways to get close and be near you, it's likely that he's attracted to you.

Pay attention to whether he's doing bold things in front of you. When a guy is interested in a girl, he will try to impress her. This could include risky actions, like jumping off a cliff into water or riding on the trunk of a moving car, or any other daring activity to catch her attention and make her wonder if he's getting hurt. If he's not typically someone who takes high risks but does so around you, it’s likely he’s doing it just to impress you. Watch to see if he looks at you after performing a risky move—this indicates he's trying to grab your attention.

Assess if he's flirting with you. A guy won't flirt with a girl he's not interested in. If he's flirting, he might be testing whether you like him too. Playful flirting can help him mask the fear of rejection when confessing his feelings. Look out for whether he's enjoying your company, teasing you, and making you laugh.
- Make sure he's not the type of guy who flirts with every girl. If he flirts with everyone and that's how he interacts with women, then it likely means he's not flirting exclusively with you.

Notice if he gets jealous when you're with other guys. Does he seem upset when you're having coffee or lunch with a male coworker? Does he keep an eye on who you're with? If you have a male friend, does he seem uncomfortable around him? He might not show his jealousy openly, but if he's really jealous when you're with another guy, he will pay extra attention to who you're hanging out with or act distant when you talk about plans with someone else.
- Every guy reacts differently when jealous, but if you notice that he's jealous, that's a definite sign he's developing feelings for you.

Check if he gives you small gifts. If he brings you flowers or cute little gifts that make you smile, that's a clear sign he's attracted to you. Is there any other reason he would spend time picking out a gift for you, knowing it will make you happy? He might act humble when giving you the gift, downplaying it in case you refuse, but clearly, he's doing this because he likes you.

Evaluate whether he acts like a gentleman when he's around you. If he holds doors open for you, opens the car door, pulls out your chair before you sit, offers you his jacket, and demonstrates other polite and considerate gestures, it's a strong sign that he likes you and wants to take things further. Be sure to observe if he's acting this way exclusively around you, not just in front of other women.

Observe if he takes care of his appearance when he's with you. If he smooths his hair, brushes off dirt from his clothes, rolls up his sleeves, adjusts his belt, or cleans marks off his shoes, it's a clear signal that he cares about his looks and is possibly attracted to you. If you notice him checking his reflection or paying more attention to his attire when you appear, it's likely that he's trying to look his best because he likes you.

Pay attention to whether he matches your pace. Research shows that when a guy walks with a girl he's interested in, he will adjust his pace to match hers, either slowing down or speeding up. However, when walking with casual friends, he won't make this adjustment. Next time you're walking together, take note of whether he's walking at the same speed as you!
Learn his body language.

Check if he stares at you. If he's interested in you, you'll probably catch him staring at you from across the room. Of course, you shouldn't be too obvious in trying to catch him looking at you, or he might think you're staring at him (and assume you're the one who's interested). If you notice him looking at you a few times, it's likely that he's attracted to you. Other signs include him quickly looking away or showing a shy expression.

Notice if you catch him staring at you intently. If the two of you lock eyes and he keeps staring at you to the point where you feel a little shy, it's likely that he wants to keep looking because he's genuinely interested in you and wants to take things further. Of course, if he's feeling embarrassed, he might glance away for a moment, but if he continues to stare at you for a few extra seconds, it’s a strong sign that he's attracted to you.

Observe if he leans towards you while talking. When a guy likes you, he will subtly—or even clearly—lean towards you while conversing. This is a basic gesture of interest. If he likes you, he will lean his shoulders, face, arms, and body towards you. If he turns away or steps back, it’s likely that he’s not interested in you.

Notice if he seems restless when he's around you. If he's constantly adjusting his shirt, blushing, picking at his skin, fiddling with something on the table, tapping his feet, or just generally acting fidgety, it’s probably because he's interested in you. These are basic signs of nervousness, and if you're making him feel a little anxious, he’ll likely be more fidgety than usual because he's excited to be around you.

Pay attention to whether he always finds excuses to touch you. If he's truly interested in you, he will do whatever he can to get closer to you. He might touch your back as he enters a room, give you a gentle pat on the shoulder or arm, or even stand close enough for his foot or leg to lightly touch yours without pulling away immediately.
- He may even tuck a stray lock of hair behind your ear if he’s really trying to get closer to you.

Notice if his face looks "relaxed" when talking to you. Watch if his lips part slightly. This is a basic sign of interest. If he likes you, he will subtly open his lips when making eye contact or conversing with you. Also, pay attention to whether his nostrils flare as you talk. Observe if he raises his eyebrows slightly during the conversation. All of these facial cues indicate that he feels comfortable around you because he’s really attracted to you.

Check if he keeps making eye contact with you. While you’re talking and standing near him, see if he tilts his head, shoulders, or feet towards you. If a guy likes you, he will naturally try to get closer to you. If he looks away, turns his face, or faces in the opposite direction, he probably isn’t interested in you.
Analyze his words.

Notice if he asks about you. Has he ever inquired about you with your friends? Does he ask if you have a boyfriend? If so, he’s definitely interested in you. You may need to check with people around you to see if he’s been asking about you. If he is, it’s a sign he wants to know more because he likes you too. However, if rumors say he’s been asking about you, chances are high that he’s genuinely interested.

Observe if he talks a lot when he’s near you. He may be so attracted to you that he rambles on about his favorite movie Star Trek or his relationship with his younger sister. This endearing behavior happens because he’s so focused on you that he loses control of his words. He might even apologize for talking too much, saying something like, "I don’t know why I’m telling you this" because he realizes he’s acting silly in front of you.

Find out if he’s open with you. If he has feelings for you, he might share personal details he usually doesn’t tell anyone. This shows he wants to learn more about you and hopes you’ll understand him better. If you notice him being open or saying things like, "I’ve never talked about this with anyone" or "It’s been years since I mentioned this," it’s likely because he likes you and wants you to know him more.

Pay attention to whether his voice becomes deeper. Research has shown that men tend to lower their voice when speaking to women they are attracted to. Next time you talk to him, listen closely to his tone. You can compare how he talks to you versus how he speaks to his friends or other women to spot any difference. If there’s a noticeable shift, it’s likely he has feelings for you!

Notice if he regularly gives you subtle compliments. He may not directly say, "You’re so attractive. I really like you." However, he might offer you subtle compliments to show that he truly cares about you. He could praise your unique hair color, your laugh, or your always sunny disposition. Keep an eye out for an increase in these little compliments – it could be his way of expressing his feelings.

Observe if he laughs without reason when he’s around you. If he likes you, he’ll likely laugh more often because he enjoys being around you. When you say something funny, he’ll laugh loudly, or even if what you say isn’t funny, he might laugh just because he’s nervous. These are signs that he may have feelings for you.
- However, he might be so nervous that he won’t laugh at your jokes because he’s too concerned with what you think of him to pay attention to what you’re actually saying!
