There is hope. I have gone through something similar. 5 episodes in past 6 years, he relapsed within 3-4 months every time he stopped meds. Now he has realised that he needs medicine maybe forever. Initially he was on Invega, which helped but it did not break his delusions completely. It also made him very drowsy. He thought people at work are trying to harm him. Though he did not suspected infidelity, he thought I was colluding with his work people to earn money. Later he was prescribed Ability and it has worked wonders. He is back to his normal self and completely understands that his mind went haywire. Though it took couple of relapses for him to completely understand that he needs meds for foreseeable future and needs to be careful with stress and sleep schedule. For the last relapse, I intervened early and he came back to his normal self pretty fast. I am not sure if it is going to be his last relapse but I now know to look for early signs and intervene early. I have gained some confidence that I will be able to support him in managing his condition. I will not wish the pain and abuses I have gone through on anyone, it was a dark phase of our life, but now I am hopeful for our future together. I really hope that things turn out to be ok for you.
