I willingly give you my support.
Does your health prevent you from learning to drive. I know someone who learnt in her 60's, took one day at a time, she passed her test and couldn't believe it, she's a capable driver now in her late 70's.
When a situation seemes impossible to change or escape from, doing one tiny thing can help ease the bigger picture.
This man sounds like he has ground you down, so much so that you can't hear anything but the abuse ringing out in your head.
Make some space for something else, don't worry if you take the eye off the ball with him, you sound in hyper viligent mode, he will carry on exactly as he is, have faith nothing will change if you don't keep tabs on him, I understand there are probably many aspects whereby this man needs monitoring, Im sure his abuse covers many areas but take a rest and sit and think about you, and something for you.
I'll ask first op, what do you like ? what do you like doing, music, telly, crime shows anything, tell us, because I bet you're more interesting than that husband of yours, you've just forgot, or been made to think you're boring by that horrible shallow, cruel man.
