pony, good to hear from you, totaly get what you mean about getting yourself back. I realise my life was so highly organised around FW that I need to find my own routines, de-withdraw myself and start seeing friends again etc. I think, I hope, that healing is a process and the balance will tip from thinking about FW to actually concentrating on yourself.
mrsm, it feels hard because it is hard. You can't just go back to how you were. The hard thing is disassociating what he wants (he can't decide, therefore emotional seesaw for you) from what you want. We are so conditioned to focus on their needs.
ER, good to hear from you. Glad you are feeling less depressed. Post as much as you like, it is heartening to read.
mink, what you wrote about conflict was helpful, esp re book-buying, looking for solutions without being entirely sure what the problem was. I remember buying a book on step-fathering, because of the conflict and tensions around his relationship with dd. It must have been 3 + years ago, possibly 4. That is a really horrible realisation, because it means on some level I knew and I tried to make it okay. Though I also knew it was not okay.
Which brings me to the why does one stay part of your post. Because they need you to stay. For me, I grew up in a household where disobeying had catastrphic consequences. The behaviour patterns were the same. And leaving is hard, because you are not allowed to leave. I am still fighting to leave, psychologically, he is trying to control me and the situation, and I am struggling to assert that the situation has changed and he can't control it. And it makes me feel sick to the stomach.
So to come back to what you say pony, I think it is important to change the routines, changes (hopefully) the thought patterns, but this is really hard and that is where you need support from others, at least I do. I probably need more RL friend support instead of hiding away, though.
