What should I do if my best friends be friend with my enemy?

Sounds like your best friend may also be an enemy.

Well firstly, if you have a problem with C but A&B don't, you can hardly expect them to drop C like hot toast. So the only question is, do you dislike C so much that you are prepared to cut yourself off from A&B to avoid them?

Or is there a possibility of a reconciliation with C? And would it be worth the hassle to get back with A&B? I can't answer those questions for you, but those are the things you need to consider.

you feel betrayed by a&b, don't you? i can understand that. my sister kept up a friendship with one of my exes, even though she knew how much he had hurt me. she knew him first, but i felt like her loyalty should have been with me first and foremost, and it pissed me off that she didn't seem to see it that way. the only reason it's no longer an issue is because he's dead. i guess it comes down to which is more important, your friendship with a&b, or their refusing to stop seeing c. you could hang out with the first two without c being involved. and i think that if they have any consideration for your feelings, they should be able to compromise on this situation.

find some new friends....

dropping your friends A&B because of C would only isolate you and eventually cause you anger/hatred towards many. I think the best thing to do is explain to them how you feel about C, but not to persuade them in any direction. Explain perhaps that you feel uncomfortable with C. And if you must come into contact with C because of A&B, remain cordial. Just because you dist est a person, doesnt mean you have to be... well, mean. you can still play nice and maybe slowly, if forced to do so, and depending on the circumstances, maybe reconcile your differences.

think about this bro...is what c did to make u so pissed worth losing friends over? i mean if u can work that out then work it out. dont be stubborn and just ignore him. drama's never needed in life bro. tell c u wana be friens and i bet u guys all are abcd together buddies

Maybe A&B are good friendly people who don't want any more trouble than neccesary. God says to love your enemies and forgive those who hurt you, and that blessed are the peacemakers. I wouldn't fault them for staying friends with C, unless they do something awful towards you.

i am in the exact same situation, right now. i am in the process of erasing my two best friends because they have made it very clear to me that being friends with my enemy is more important than being my friend.

its their choice.

i myself had to come to this conclusion over the period of a few months though. i realized that i have an unhealthy dislike for my enemy, and that i cant have her in my life in any way. i told my friends this and they dont take it seriously. regardless, i am severing all of my ties with my enemy, so if i am that important to my two best friends, then they will stick around.
