Well, it depends. If she tries to make a move and your not interested just be honest and tell her you don't feel the same. But if that doesn't happen and she just keeps flirting then just find the right time to tell the truth.
Yes....he can be....it's a possiablity
That is simple. Tell her how you feel.
It means he is a cheater. Steer clear.
Always tell her stuff about your girlfriend it is a subtle way for her to get the message. Simply telling her "no" is very effective.
Be there for him when he is sad, still show that you care for him, it doesnt always work, but that can get into a guy's heart answer:
She likes you but what ever you do,do not tell your brother.
hes bisexual
Ya, but if he flirts with you WHILE he has a girlfriend then that isn't good
tell on him and tell him leave my girlfriend alone.
he doesn't respect his girlfriend nor their relationship, and if you were to become his girlfriend, he would treat you the same way.
umm, tuff one. well a gay boy has a much fitter body and a straight boy flirts with you and is a show-off. hope i helped:D x
Its really up to you if you are not gay or not into males simply ask him to stop flirting with you do not flip out or get mad at him just tell him not to do that.
