Those are good questions to ask, although you have to trust that your potential spouse will be honest with you in his/her answers. And one thing to note about abuse: It doesn't always show up early in the marriage, or at least you might not recognize it if it's really subtle. Some marriages go for many years before abuse starts. People change over time, and sometimes those changes aren't compatible with you. A successful marriage takes work.

I think, another question that's good to ask, if you don't find out before marriage, is, "If you and your partner are in bed, and your feet are cold, do you warm them by sticking them against your partner's legs?" If you don't like being shocked awake by icy feet against your warm skin, you better not marry me, ROFL!
