I kinda know how to proceed in general but I figured some of you might have the perfect tactic.

About two weeks ago I went to a meetup through a social app to see some concerts with randoms. Didn't check for days before the event, so didn't know the meetup was closed. Went there and it was just me and a girl who was in the same situation. She was a 6.5, but really cool. I thought whatever, let's make it fun and started to game her. She was really into it. I escalated as far as I could without making it sexual because I didn't want to sleep with her. On the way back she physically prevented me from leaving the bus at my stop so that I would have to ride with her to her stop. She wanted me to go toher place. Anyway, long story short, I declined, and she didn't say goodbye. Then an hour later she texts me, saying thanks for the night, drive safe blabla. I gave a simple "Home safe, thanks" (been drinking).

I didn't fuck her because I'm in a LTR and had decided to stop cheating. I had a talk with my father about it, and some things he said made me think that it's okay again. So yeah, I wanna plate this chick. What should I do?
