Your friend should accept her for who she is. I hope you and your guy friends relationship doesn't get destroyed from your girlfriend and your guy friend from argueing. If your guy friend can come up with a good enough reason why he doesn't like her...then talk to your girlfriend and see if she can change that. I hope that she can understand what is going on and everything works out.
if they are your best friend they should understand
just tell him and get over it you should feel happy for her she is your best friend
Is this guy worth your relationship with your best friend? Think about the consequences of dating this guy and what could happen if you find out he was just flirting with you.
you should try asking your boyfriend to talk to him
no
Talk to her about it.
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.
It depends on if it would make your friendship be all awkward if he doesnt like you back but if you think he does then you should because if you love him then he should know it
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.
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.
Neither of you should get to date him.
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.
