The only thing to do with triggers is dismantle them so they're not triggers. You have to decide what you want regarding your husband and work on that. Is he going for treatment, complying with it, have you been given an idea of when he will be more stable? It's a "problem" like any other and needs to be dealt with, whatever happens, as it happens, not before. Don't let yourself live in the "future" where worry lives, thinking about what he "might" be like when you get home. When you get home, deal with whatever you find as best you can for YOU.
