Because he's intimidated and feels you may fall for one of your guy friends. Self esteem issues. or it could be a number of reasons.
Me being a guy I know- it means he likes you and can't take aeein you talk to other guys if you like him get to know him more
because he likes you to! :D
cuz hes into you, moron.
maybe he really likes you and doesn't want you to be with nobody else but him because he really cares and love you so much and want to be with you
that means he probably likes you. you should ask him
You can tell when your best friends are jealous of you by how they talk to you and how they act around you.
Erm im going to answer this question with another one. Why would you pretend to be jealous? If you really like this girl, im assuming its a girl i could be wrong, you wouldn't need to pretend to be jealous. And you don't need to show off, she'll like you for you not who you pretend to be.
Because they are just plain wierd i mean i never would do that to a girl.
Probably, yes. Or he's just annoying.
in my oppinion its probly because he is used to getting all of your attention not liking the idea of having to share it with what some guys may view as competition!
Because he is possesive,dominating, and insecure. He needs help, You RUN.
Yes a guy can pretend to be jealous it just depends how easily he can cover it up for you to tell weather or not he is really jealous.
