could use support

my boyfriend and I suffered from shared psychotic disorder about a year and a half ago. We are trying to patch up our relationship because he feels betrayed that I "made him crazy." My mother has schitzophrenia. I know that now that we have come back to reality by ourselves, it proves there is hope for me and for him. He also feels that I made the relationship unsafe. I understand, but at the time, we were living in a small room non stop with no interaction with others. Although I feel that what I did was wrong, dragging him into my delusions, but I am wondering if he has responsibility because he caused quite a lot of stress talking about how depressed and suicidal he was. We are both making so much progress but he feels like we never dealt with it all because we never talked to anyone. What can we do to overcome this.
