When the bestie is involved:

My best friend likes the guy that I like.
And he likes me but not her.
We want to get together, after he's sorted things out with his ex.
But we also have to wait for my friend to be okay with it . . . the other day we were txting . . .
she said "It hurts because you'll have a chance with him and I never will"

She doesn't realise that we're also waiting for her to feel more comfortable with it before we do decide to take the friendship further.

It just makes me sad because of ALL the sacrifices I have made for her, and she can't help herself from getting involved now.
My other friends are saying "be selfish for once" but I can't, I can't do that to her.

Well it is good that you are waiting for her to be okay with it but look at it this way, how long is he going to wait?

If shes a true firend, she will understand that this is something special to you. she shouldnt guilt you into holding back just because she isnt getting what she wants. if shes a real friend, she will just want you to be happy, and if shes going to stand in the way of that happiness, thats a little selfish and wrong.

. . . well whats happened is she said it's okay, so we are going out now (WOOT) but I still feel bad for her . . . but I'm so conflicted because just last night she made out(& other stuff) with two guys, not at the same time but in ONE night! . . . I really pray that she is truly okay with it . . .
