So last week, i kissed this girl who was my friend in a really spontaneous way. we had a great week talking/texting/socializing, and then the next week she was really distant.

Come to found out, she's getting back together with her ex boyfriend.

I don't know whether to ignore her, act normal, or to tell her how i feel. i was kind of thinking of saying something along the lines of, "i'm glad you and you're boyfriend are back together. Which is great cause he makes you feel special(he doesn't). You like him a lot. And you obviously feel nothing when you kiss me, right?(which i'm pretty sure she does feel something)"

Really like this girl, and i know i'm a "yes" so what do i do?

hmmm... I'm going through the same thing friend. I feel ya on this. You could try letting her go, or you could esculate from where you left off at(and ignore the fact that she's getting back together with her ex), or you can try going for bf destroyers. There are alot of ways to deal with a situation like this. But its just my thoughts. Don't bash him though. Telling her that he's not the right guy or pointing out things that make him look bad will only make her take his side and defend him (trust me, I learned that through experience) and most of the time will push you away from her.
