I really appreciate this actually. I guess my partner's view is "she lets people walk all over her and a mature/adult/person who deserves to be in this relationship would be assertive and get out of the car (or even walk home)."

Which, I think, is fair from him too. He's not in therapy right now but agrees its time for him to work on stuff too. On one hand I guess this standard from him is really high, on another hand, isn't it basic decency to do what you say you'll do to take care of other people, even if a little unreasonable? I said I wouldn't let it happen and I did... I just want to figure out what to do so that it doesn't happen again in the future.
