Husband severely dislikes me when not medicated

My (soon to be ex) partner and I have been together for 13 years and have young kids. About 12 months ago a few bad things happened to him and he fell into depression and got quite angry. A lot of resentment and anger was directed at me.

He went and got medicated and when on anti depressants he treats me ok and seems happy but when transitioning to new meds he is quite mean and seems to have a lot of really negative and untrue feelings about me. For example he will accuse me of just keeping him around to be his servant or if I ask him to do something as a family he will say I’m trying to manipulate him so I can use him etc. This is absurd and especially in light of the fact he’s been so depressed he really doesn’t do a lot of housework or other things.

In December he went off his meds, treated me awful all month, accused me of treating him badly if I said anything - and is now demanding an immediate divorce for his mental health and we immediately sell our house. He can’t see his role in any of it and seems to think I’m the worst person alive. There a whole bunch of reasons to do this slowly and think it out- including the wellbeing of our kids - but he won’t hear of it.

I’ve accepted there’s nothing I can do but has anyone else experienced a partner channel all their negative emotions towards them? He has no family or close friends and I’m his only real support network.
