Man I feel your pain....the little things like cooking food that irriatates her is really small stuff. All this is a game and it sucks I know. If it were me I would confront her. You can't change what she does or how she feels. But you can let her know how you feel and and put the ball in her court. For me it would be a deal breaker and I would show up at his place just before her and say "thanks for the commitment" and walk away never to look back. Thats just me and I shot for the hip....probally why I'm where I'm at but hey it's my life. Best of luck whatever you do...just don't let her erode you any further and get away with it
