I'm no veteran, but besides GAL...what, if any, 180's have you been able to focus on? You have to make changes for you, but you should look at things you aren't satisfied with and work on them. I think reading and joining a gym sound great, but what else are you thinking?
I like what you said earlier about having cleared off her car and then not the next time. If she is upset either way, just consider what she is upset about. If you don't do it she is mad because you didn't help her and could have. When you do help she is mad at herself for what is happening. Not saying you should do things just to make W mad at herself but if you want to do it then do...if not, don't worry. Try not to have expectations on her reactions and be the person you want to be.
