Yes boys are animals and if they see something they like they will chase after it but he is your boyfriend and tell your boyfriend how you feel remember dont hide your feelings
If he has been doing this for a while then yes If this is the first time you have caught him Talk to him about it then give him a chance
it means that he still has feelings for you, even if he has a girlfriend.it usually is a sign that he would be your boyfriend once again in life.
Because he wanted to try to date her again and wanted to do it freely. Either she didn't go for it or he got what he wanted. Either way, take your relationship back to the "dating" level and not the "boyfriend girlfriend" thing.
Well if they stare at you that probably like you so stare back and see what they do .
stare back or talk to her.
It could mean he has feelings for you, and can't help but show it by making eye contact in a loving way. If that's not the case, he may just find you have terribly interesting and/or beautiful eyes.
because he still fancies you
you tell him you really like him stare right in the eyes and kiss him
Nothing. It's not polite and very difficult to stare only at you. Noticing other women isn't a reflection on his feelings for you.
He might stare at you alot, asks his friends about you
If a girl continues to stare at you after the initial look, it is likely that she likes you.
