Don't want to be an ******?

So, I go to this wine vineyard party last night. I have no expectations for the night, not trying to attract or hit on anyone. Just there to be there. I am coming out of a marriage right now, there is a lot of indecision and drama on my part and I don't feel that I want to make any woman a part of that right now. Long story short, there is this woman there, that without even trying, we hit it off. A couple of gles of wine and hours later, we're PDA ing and end up in her car, inspecting each others crime scenes. We didn't exchange numbers, I wasn't the "first" move maker, and I really don't want to bring my drama into her life at all, but I don't want to seem like an ******. What is the best way to deal with this sitch?
