MAYBE YOU SHOULD IGNORE..
Do her in the bathroom and then tell her it's not her...it's you.
he probally would talk about her and stare at her or make fun or talk bad about her. He will always want to hang around his best friend and his girlfriend, and he will constantly chat to his best friend and girlfriend to catch the attention of the girl he likes. Male dynamics :) *sigh*
make your girlfriend jealous
and also to add from the question above he has told you he does not really like his girlfriend
go with the guy she kinda likes if she goes with the other one her friend will get mad at her and not talk to her anymore and you should let your friend be happy with her boyfriend
you do what you think is right and your best option
then he likes her. if he doesn't try anything i dont see the problem.
If you want your friend to still be your friend, hang out with him. You might find out what he likes in his girlfriend and she could be your friend too. Friends do this for each other.
He has not stated publicly who he likes the best, but he probably likes Selena Gomez (his girlfriend), or a family member the best.
In my opinioon you should find out if your best girlfriend likes him, if she does then maybe you should help things move along with them, its kind of tough but you will realise that its better to make your friends happy then to make everyone sad. Theylle be other guys, and it will be hard, and maybe you should tell your friend about your feelings and his too and see if she decides to back off. I think you and your best girlfriend should talk about it.
you need to tell your best friend that you do not like them that way.
