shes really not a best friend if shes going out with her best friend's crush new person! i object wat if she was dating him first then the other best friend got the crush!?
She's not your best friend. Find a new friend.
If your best friend liked him/her first, then let your best friend have a chance at dating said crush. If things don't work out for them, ask your best friend if it would be okay if you flirted with/dated him or her and act accordingly.
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
Then what is your problem ? I think one of them is not only your best friend but also your crush . If it is , then it is up to you what to do . If I were you then I would scarify my crush for my friend , of-course after verifying the weight of their relationship ...!
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.
talk to him and say that its not right but on the other hand u like him so talk to ur best friend first then decide what to do
Well if the guy who has a crush on YOU suddenly started dating your best friend, maybe you need to consider whether he liked you all that much in the first place, because surely if he liked you as much as you think he does then he wouldn't have started to date your best friend? but if that is the case, he ain't worth it and I'm sure you can do better.
let your best friend have her, dont let a relationship like dating destroy a friendship, friendships are much more valuable.
I say move along , I mean do you want to lose your friendship, there would be other people and you will find that special someone
Let her be with him. Sisters before misters.
i would talk it over with ur best friend and make sure she knows that u wouldn't be ok with her dating him. hope that helps ya
