I'm struggling to find advice on this. I've met a girls and we've started dating and we've become intimate. I feel bad because I did lead her on abit. While I explicitly stated I am trying to keep things casual and I'm not looking for a long term relationship she continued to escalate with me. Now I'm getting messages to meet up again to try and have something more established.

Based on the few dates I've been on I think this girl is abit naive. I dont think she fully understood what she was signing up for when agreeing to a casual relationship. I feel somewhat responsible (even though I was clear that I had not chosen her and we still had to work things out) because I didnt disqualify her. I just ran my game, the M3 model.

I want to end things without hurting her too much. It's clear that she likes me more than I like her. Any advice will be appreciated.
