I'm so tired and confused

So Sydney kissed me.
On the lips.
Thursday while at the movies.
But ever since then she's made me feel awful when I even mention it or try to cuddle with her. And then complains when I hang back from snuggling with her.
I'm so confused and I don't know what to do. I was so done getting my hopes up. I'd finally come to terms with just being friends, and then she throws that curveball at me. It actually hurts. I'm so tired of hoping and forgiving and getting broken over and over again.
I just want to forget.
