I'm in a similar position. I think being in lockdown and being forced to spend time in the same house all the time (I am still working so was normally out during the day, but have taken over 'his' study) has brought out the worst in him and all I can see is a very selfish, angry, uncaring and controlling person who has no hesitation in swearing and shouting abusive insults at our daughter (who has mental health issues, by the way) in public and then expects me to back him up.
I've reflected on this a lot in the last 6-9 months, and have come to the conclusion that, although I still love him, I don't like or respect him any more. What a strange position to be in.
I'm also thinking of leaving, but at the moment the thought of doing that is too scary.
