Don't be mad. This guy is, after all, your EX boyfriend, not your boyfriend. He has no obligation to be faithful to you after your relationship has ended. His life must go on, somehow.
You should tell her, they should be ok with it because they are not in love with their cousin and plus if she is really your best friend it will be cool with her.
Talk to your friend first. If he really is your best friend he should be able to understand the situation and figure it out with you.
Say to your bf: " Look we have been dating. I get it shes your best friend but she should stay your best friend and I can stay your girl friend. I really like you! Please don't break my heart."
If he likes you, you should run. You should run from any thought of liking him back. He is dating your friend. If he really liked you, he would break up with her and ask you out. Dating your friend means that he is committed to dating your friend and nobody else. He has knowingly made himself unavailable to you. If he actually says that he likes you, you should run, and you should tell your friend to run too. Any boy who says he likes one girl while dating another is making trouble. He's willing to cheat on her, and willing to let you be the other woman. This is not that type of guy who will work for a healthy relationship. You don't want him.
Yes you should, if you want him to know that you really do care.
If you really love (as a friend) your friend then maybe you should give him a chance with the girl or both of you just leave it behind and continue on with your lives and see what happens.
If they are dating, then how sure are you that the girl is your girlfriend? Talk to her about it; find out what if anything is happening betwen them, and then ask her whether she is really with you or the other guy. Be prepared for some disappointment.
Well, I would forget about it because her twin is dating him, this could cause a lot of conflict between the two siblings, and it's NOT recommended.
You should be totally honest. Tell her you like her, who knows, she might have the same feeling.
Secretly keep on liking him.u don't want to hurt your friend by trying to take her boyfriend.
Ask her. If she is really your best friend she would have told you and if she is your friend she'll tell you when you ask her.
if you really like the girl, you should just talk to your friend. you may never know, your friend might be just fooling around. Don't hesitate to express your feelings to the girl either. if you are meant to be together , nobody can stop it..
