As nicely as possible. Make sure to mention all of her good attributes that will help her get a new boyfriend quickly.
be nice
You should wait till they break up.
If you do not like him then yes, you should.
wait for them to break up and then see if she's interested in you.
apoligize
I don't think that you should. My friend is going through the same problem. If you ask your best friend out, then it would be very awkward when you two break up. I would suggest that you try and find another girl that you like and get to know her. And, if you did ask her out, you wouldn't want to break her heart when you two break up.
Well,what you should do is tell him and if he is a good friend then he will understand and if he likes you too then he will probably break up with that girl and get with you or wait until they break up to go out with you and if he doesnt like you like that then he should tell you straight out if he is any good of a person at the least.
if he is really into that girl then back off but still be strong friends. if that girl and him break up then after he recovers ask him out
See what your friend thinks of the situation. If your friend does not really like the girl, then feel free to take whatever action you think is appropriate. If, however, your friend likes the girl back, then for you to try to break them up would be a pretty scummy thing to do. If you're already a scumbag, then I don't suppose that will bother you.
If you really like the girl you have been with for five months, I would recommend staying with her. If you like her friend better, then break up with your current girl and begin dating the new one.
Talk to him about it. Why should a girl break up a friendship of two guys?
Tell him that you like her also. go out with the girl. Dont just think about what it would do to you. if that girl likes you, then you shouldn't put down the opportunity because girls love it when guys they like ask them out. as for your friend...well if hes your friend he''ll understand
