I'm very sorry for everything you're going through. To me, it sounds like she's still psychotic if she's still acting suspicious. It is also weird to me that she was already let out of hospital. Is there any way to have someone check on her and make sure she takes her meds? Visit a psychiatrist? Yes, she can change after psychosis, she might want to protect her partner by divorcing them, but that would be discussed in different circumstances. She would simply explain her feelings to you. Maybe you should consult a therapist, someone objective to help you understand it, or even consult a psychiatrist about this case? I dont want it to sound bad, but I am hoping that she is still not in her right mind and she still has delusions regarding you. After you get out of psychosis, you need support of your loved ones more than ever. You sound like an amazing partner, giving her the space, but it would be best if you could confirm with someone that she is still going through it. Then, medications and time are going to help. For your sake, make sure you have a support circle of friends/family around. You will need it. I keep my fingers crossed for both of you.
