It is best that you do nothing. First off she has a boyfriend and it would just be wrong to try and come in between them and second you work together which can make things very awkward. You need to move forward and focus your interest elsewhere - someone single.
If he is her boyfriend, hopefully, she would like him.
Does the girl know you like her? How long have you an and your boyfriend been together? And are you asking what should you do?
you and that girl should explain to her bf. that they both like each other. then you and the girl should try to figure out who to date.
give it a shot
If you think you should ,, then go for it! but it depends on why they don't think you should :)
If you like her then yes. Even if it's for a short period of time. Enjoy the time with her. If your mates can't support then they are not good mates
Tell him the truth, say you like girls.
Just like he does with anyone else, or he isn't really a good boyfriend!
Depends what grade you are in but just get to know the person and get closer with them. Joke a couple times about what it would be like to have him or her as a girl or boyfriend then tell them how you really feel.
lick her crotch
Nothing. You broke up with him and the other girl likes him. It's none of your business.
If the girl has a boyfriend already,try not to get in the way. If she really does love you then she will break it off with her boyfriend. Don't try to rush her though as girls don't like that. Trust me, I am one.
