@Purification that is good to hear you are putting yourself first and seeking counselling and legal aid.
sorry that I'm not overly good at offering advice. It is easier for me to answer questions rather than offering my opinion on what people should do in certain situations because I don't trust myself as being the best decision maker, let alone trying to do that for other people if that makes sense. With questions I can just answer stuff through my experience and hopefully that helps.
That is good I think that he said he is taking medication but it is very possible he isn't on the right one for him. If he is still having delusions and other symptoms, that seems to be a good indicator he needs to be on a stronger dose or a different medication.
i myself went on about 6 different medications while being hospitalised before I finally got put on the right dose and medication. It can be a long process before symptoms get a bit better and even longer if he doesn't want to be on medication because he can just stop taking them and it does not take long at all for symptoms such as delusions to come back.
triggers are always going to be a big thing on or off medication. So it's good to be aware of that.
i myself have never forgotten anything I said or did while in full blown psychotic episodes. But I did talk a lot with a girl when I was in hospital who also had schizophrenia and she said she could not remember a lot of stuff. So it is possible that some don't remember or that they try really hard to block it out.
what is your gut feeling on him being sorry and wanting to fix things? Do you still want to be with him? If so, he is lucky to have you but if you don't want to be with him I would back off from him as much as possible or he might get the wrong idea.
you said you don't know what to believe so maybe just go off your gut feeling and do whatever you feel is right for you.
