well this has or is happening to me my advice would be to just wait for your time. Ask the friend if its ok if you date him so there will be no friend problem's.
I think you should ditch your best friend and replace her with another person who won't betray your trust by dating your boyfriend. That's what you should do.
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.
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.
Well, frankly I don't think your friend is good friend if he is trying to take your girl. Maybe you should find another friend who will respect 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."
Yes you should, if you want him to know that you really do care.
i dont have a friend that has an ex girlfriend that is dating his friend when your friend is on a summer vacation so i cant no no no no no a
If he likes both of you it is best just to all stay as friends for the sake of losing one another for dating reasons...
if they are your best friend they should understand
Unfortunately there is nothing you can or should do at this point as you should have professed your feelings before introducing them - now it seems they are dating one another. For now you will have to let go and try to focus your interest elsewhere.
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.
