There are so many instances when a confident guy turns into mush and he morphs into a complete nervous wreck when he is around a girl that he likes. Here are some of the possible reasons why a man acts nervous when he is around a girl that he likes.
Its against his instinct to express his feelings
The first and the basic reason why men begin to act nervous around girls they like is because it goes against their very basic instinct to express the way they feel. And since they are trying physically to do the right thing and act the right way they get all nervous and edgy.
He is desperate to create a good impression
A man also begins to act nervous around a girl that he likes because he is desperate to create a good impression on her. This need to impress puts a lot of pressure on him and hence leads to all the nervousness.
He wants her to see his perfect self
When a man is around a girl that he likes he wants her to see his perfect self. He wants to be the man that she would desire and want to be with. Since he is aware of his shortcomings he wants to make sure that they are never revealed and this makes him nervous around the girl that he likes.
It is the excitement that makes him nervous
When a man is attracted to a girl he is excited about being around her. The closeness and the physical proximity that is created gets his adrenalin pumping and makes him feel excited and nervous.
He is afraid of rejection
A man also gets nervous around the girl that he likes because he wants to be sure that he makes a good impact on her. He is still insecure that she might reject him and his advances and since there is an emotional investment here he is unwilling to take that chance. Hence he feels nervous around her.
He feels very vulnerable
When a man likes a girl he becomes emotionally vulnerable. As soon as he himself becomes aware of this emotional vulnerability he realizes that he is not his own controller anymore and hence feels nervous around her.
He feels out of control
A man also gets nervous around a girl that he likes because he feels a little out of control and out of sync of his regular feelings. This makes him feel anxious and hence leads to all the built up nervousness.
