Been going out with this chick who has treated me perfectly. No games or drama whatsoever, incredible sex, she looks up to me, compliments me, I'm on purpose, etc. She seems like a genuine good person and my family approves(including my dad whos been around the block). I made a huge mistake by cheating on her and it was with my ex(fucking STUPID- not dealing with ex ever again). Felt bad about it and told her(stupid again). I apologized and told her it wont happen again. Looks like she is giving it another chance but said she does have some doubts because it hurt so bad(shes been fucked over bad in the past and as far as I know she has never cheated on anyone). I can tell this devastated her and I'm really upset I did what I did. She is still there and looks like she wants it to work out.

My frame has been pretty much perfect. How can I prevent myself from losing frame here going forward? I assume its dont dwell on it, usual dont act needy or desperate/afraid of losing her, etc etc. and don't apologize too much or act blue pill at this point. What is the proper play?
