I've just read the thread in one go, and a lot resonates with me.
My ex was abusive, but there was never any overt violence. But the undercurrent was there. He's physically stronger, liked pretend wrestling me that I think was about showing his strength, and on a couple of occasions threw stuff.
I get you, OP about the food. Ex liked going shopping as a family, I hated it. I could do the shopping on my own in half the time, and at half the expense. (We had separate bank accounts and I was expected to pay for all the food.) One time, he'd put no end of things in the trolley just for him, then when DD put in a single, 80p box of breadsticks, he told her to put it back, we weren't buying those. for no reason, it was just because he could. So I picked up two boxes and put them in the trolley. He said nothing after that, and that's when I began to realise I was more in control than I thought.
Went to a wedding, just DD and I, as ex didn't do weddings. I had that internal timer spoken of, and started getting anxious, leaving before the end. I wore a dress, the first one in 30 years. Everyone told me I looked nice, and looking back the photos look great. Ex told me I looked like a sack of potatoes, cue instant deflation.
I walked on eggshells, the DC walked on eggshells. I suffered financial abuse and will never get that money back (thousands), we weren't married. Emotional abuse, verbal abuse, and so on.
I recently found out my late MIL thought ex was hitting me, and she'd told my dad. Wish one of them had spoken with me earlier, that would have helped.
After 3 years single, I've managed to get my head together now and am planning for my future, up to now I've been in like a recovery phase. The DC don't speak to their dad, they saw it all, and some of the abuse went their way (especially to DD).
I love being able to make my own decisions. I enjoy indulging in the TV shows, and other stuff that he thought crappy and stopped me watching. I especially love not having to perform in the bedroom or suffering his groping. I like sex, don't get me wrong, but not with him.
OP, once you're on your own, I reckon you will thrive, you actually show a lot of clear headedness, despite that he leaves you feeling confused and out of focus. I still don't talk to ex as he always had a way of twisting what I said, and leaving me feeling like I couldn't argue against him.
