Like today, went out and got lunch with some girl I've been seeing/vetting. Lunch and coffee were fun great laughs and such. When I dropped her back off we got on the topic of commitment and shit like that (we've already fucked).

I was trying to put things into perspective for her, if she was just a piece of ass I wouldn't be doing some of the things I have. I've tried making this clear from the start.

Anyways throughout the whole conversation I'd say something like "if you were just a piece of ass" - "oh wow really? You're such a jerk" when the end of my sentence was "I wouldn't be doing things like rock climbing with you"

This just went on and on in circles because she wouldn't let me finish my fucking sentence. It was like I was being shit tested and picked at for trying to explain "congratulations I don't view you as a total slut and I see something of value in you".

Eventually I just said "well you're already late and this is getting nowhere, I'll talk to you later." And she got out and I drove home.

Where the hell did I go wrong and how can I improve? What the hell is even happening when this occurs?

You just treat her nonsense like a shit test? She was getting all worked up over this and I've just been trying to let nature run it's course and have fun. I think I'm missing something.
