There is a lot that cannot be truly understood unless it's been experienced. Mental illness is one of those things.
Depression didn't find me until well into adulthood and, by that time, I had been married a long time. However, no matter how much my husband reads or has explained or witnesses, he will never truly know. And it's not just knowing, but it's also a lot more work, both mentally and physically, than before. The same goes for you.
To be perfectly honest I have a deep, deep admiration for those couples that are beginning their lives together knowing, or just discovering, a mental issue. It's no picnic, for sure. Your husband will have to work at improving (and he will have to want to...), and you have to know that he won't do it in the way, or in the time-frame, that you would. You will be frustrated.
If your love for each other is not stronger and bigger than what he's going through, then it won't work. I am not saying that you will not have a happily ever after with him, but you both may need a break from the pressure.
Therapy works for a lot of people. When there is no "fix" for problem, you have to try everything that might improve it. It's my opinion that it would not be wise to discount ANYTHING when it comes to treatment.
But that's it's own discussion...
