The question is.. why is he dating your best friend if he likes you?
After that's answered, think to yourself.. who's more important? Is this guy your soul mate? Is he worth losing your best friend?
First off, confront your best friend about it in a tone that suggests you're heart broken over it. Once you get him/her to understand that you honestly don't know what to do.. discuss with them how the boyfriend feels about you too. Yes, you'll most likely end up hurting him/her when you inform them of it.. but, it'd be wrong if they didn't know the truth.
After doing this, your best friend will most likely be upset. Now it's your decision.. do you want the guy or not?
If you do:
Explain that you're madly in love with him, and he feels the same way. Make sure the guy is willing to go out with you first before doing anything else. When that's done, ask your best friend for permission to date him. If she/he says yes, congradulations! If they say no.. well, are they important to you? If they are, I wouldn't disobey their wishes.. but it's up to you.
If you decide he's not worth it:
Your best friend will probably be done with the guy, and since you are too now, there's no need to keep him around. He'll probably remind you guys of "that one time you let a guy get in between you", and that's not good. Make sure he stays a friend, but one that stays far, far away. You and your best friend most likely need time to get over him, and regain the trust in eachother.
Neither of you should get to date him.
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...
Find another guy, just incase he might be two timing
well if you like your best friend then you should go out with him|her... but if you don't your best friend then you should tell him|her, that you are going out with someone already.
It's about a guy who likes a girl, but she's dating his best friend.
Save some time and leave him. there's really no point if he's just trying to get at your best friend.
if there is a chance of your friend being with their crush back off if there is not or only a small chance or their crush likes you then tell your friend i told my best friend she was fine with it i mean its only a crush its not like they are actually dating
Well, the answer is clear... ask your friend if she's ok with you two dating. If she says yes then go for it. But of she says no, then the answer is no
Ask if you like him for him, or like him because your best friend likes him - then either ask him out, or do not.
You have to tell them
dating a best friend works every time
see what is more comfortable for the both of you, being bestfriends or dating.
