I've wondered the same thing. I was horrible to my dh, just horrible. I'd say and do the most awful things. I was completely out of control. I was cruel. Then we'd have our good days. Later on, I was medicated, and so much better.

My dh said he would never leave me, and he has never even considered it. He's a strong man, much stronger than me. My thinking is, he has seen me through my worst. Why would he leave me now?

With my boyfriend many years ago, I was so convinced that he was going to leave me that one day the door wouldn't be unlocked. I was sure he had changed the locks on me, and I sat sobbing on the back steps for over an hour. He came home and I just needed to push in on the door more. They key worked fine. So I know what you mean.

It can be hard to believe that someone can love us at times. And it may be true that your so will leave, but it's also very possible that he'll stick around for a long, long time. Love is stronger than we give it credit for.

Just saw your above post: personally, I'd share my concerns but in a very caring, not too dramatic way. I might say something like: "I want to check in with you and see how you're doing. I know I haven't been the easiest person to live with lately.

Just my 2 cents.
