Just venting, schitzoaffective partner relapsed

Hi, just need to vent. My partner of 14 years just relapsed with his scitzoaffective disorder. Had been perfectly well for 3yrs8months. Despite my objections he went os to visit family for 9 weeks. Within 24 hrs of return he in full on psychosis. His psych thinks just the pressure of his family and out of his routine triggered it and should bounce back quickly. He seems better everyday (been 7 days) though I'm so stressed about it. The problem is I've realised I just can't go back to the way it was when he was ill. I'm fine when he well looking after him - doing his medication, putting no stress on him at all (he doesn't need to work, I do everything around house etc). I've just been so anxious since it returned, and it like has triggered a post traumatic stress thing for me as I think how bad it was when he was previously ill. I can't go back to that. I feel mad because I told him not to go away so long as it too dangerous with his health. I feel he just thinks at end of day I'll pick up pieces. Annoys me that he doesn't take responsibility when he is well. Anyway just a vent. Sorry I sound selfish given the hell so many on here are going through. Cheers
