Saw him kiss another girl...should I rat him out?

tough one but i think u should tell her because she sounds like shes worth it

talk to HIM. ask him about it, find out where he stands. i think it would go over best if he told her himself, esp. if hes planning to leave hes gf for this other girl.

if you tell him what you saw, it might motivate him to tell her. and that will hurt her less, i think, than to find out in the other way.

dont just tell her. if he swears up and down it was a one time thing or something, you could keep quiet. make him tell her himself if anyone says anything.

BUT if you talk to him and he won't tell her, and you see him with the other girl again, then try to find a delicate way to talk to her. like, "i saw him with another girl recently, it might be nothing, but you could talk to him. see if its anything important."

Stay quiet, unless you want to ruin your friendship with him. He'll say that you're acting out of jealousy

tell her

she deserves to know that.

if ur close with his family u will eventually b friends again if he gets mad

I doubt your statement that you don't want to "get in the middle."In fact, I think you would like nothing more than getting him in trouble. Why is it your job to be romance police?

Tell her of course!
