Do men act nervous around you when they have fallen for you and do not want to admit it?

Yes, but the opposite isn't true. If someone is nervous around you it doesn't mean he's in love with you. Especially if you've ASKED him (what do you mean by "do not want to admit it?") he may be nervous for very different reasons.

Yes, absolutely true. A guy even shivers around the girl they have fallen for, you can see the hands tremble.

I kind of have a dilemma from the other side, I sit by her every day and I get so nervous that I don't even talk to her. I try but everything I have to say just doesn't seem good enough. It only happens around her, I can talk to anyone else, girls, guys, whatever. She just freezes me up. So yes, guys do get nervous around girls they like. Yes, they do. However, a guy can still gets nervous around somebody even if they has no special feelings, simply because that's the way they are. If he's only this nervous round a person in particular, either he really likes the person. Hack, yes we do. I'm sort of in that situation now, look for blushing. Even a slight blush means something, even talking to you or being near you could make him blush. And if he has pale skin it is easier to tell. Scotsmen have it bad. Yes. Either that, or look for mood swings when you walk into the room; works better if you catch him off guard. I could be having a really cruddy day, but whenever the girl I like comes up, I try to shrug it off as much as possible. I used to get nervous around her, and I've learned to mask it, but I'm still always really nervous inside. Sometimes quite the opposite! If I'm in a situation where I don't want to admit attraction yet, I'll usually act apathetic or disinterested, or change the subject to something innocent like classes or work. If they're acting nervous, they like you. If they aren't, there's a good chance they like you anyway. Yes they do. This is from a guy's point of view. I like this girl and when I talk to her I try to make it seem like I'm talking to a group and not just her. So then I can point my face away from her and at the other people. Another thing is when a boy did something amazing and they tell their friends, they'll try to have the girl they like near when they say it.
