Psychotic spouse

My husband went into his second psychotic episode. First one happend few months ago where he wanted me far away from him and turned completely against me and was saying I am evil. Weeks after hospitalization he showed deep remorse and said non of it was true and he loves me deeply and never wants to divorce. Few months later he fell into another episode (milder though, cause this time wasn't cannabis induced). He immediately filed for a divorce despite all his promises. Started posting weird things on his social media which really doesn't represent him. Then he was hospitalized again. But this time he shows no remorse and is continuing with a divorce. It's been 2 months now. I don't what is real and what is not. I believe now he really wants a divorce. This has taken a serious toll on my mental health and I have developed PTSD. Do you have any advice for me? I appreciate any kind help.
