What a night!

I've been talking with this woman for a few days now, and I really pulled off a maneuver tonight. I completely opened up to her. My past, my mind, my personality, just me as a whole... I spilled it all. And I might be mistaken, but I think she accepts me for it, or despite of it. This is a feeling I haven't had in so long, I don't know what it's called anymore. I guess "understanding" is the closest I can get, but it's more than understanding. It's more like knowing. I know so much about her, and she now knows so much about me. Does anyone know what I'm talking about?
