A few years ago I was in a relationship with this guy when I got really sick and had a psychotic break. I started believing all sorts of delusions, including that he had run off with another woman and died. During this time I approached another patient I was attracted to, but couldn't do anything with him, because of the staff. I would not have gone after this guy had I known my boyfriend was alive. Then the delusions subsided and I called my boyfriend out of guilt. He said it was cheating and so I tried to make it up to him by inviting him to the hospital to have sex. We did and then soon after I got out he asked to go on a break. A few weeks later I saw him on Facebook tagged "in a relationship" with another girl. When I confronted him he said that he didn't want to trigger my mental illness.

Did I cheat? My therapist said I didn't but I'm not sure I really trust her. I want to know in case I need to apologize again. Also, what do I say when this topic comes up on dates?
