I think the OP is a woman, and in the OP she is simply ranting about her husband failing her and making excuses that the failure was society's cause.

Somehow, naturally, the man is usually the head of the marriage. It is his responsibility, first, to understand his wife enough that he can make the marriage work. And, the wife instinctively trusts this. So, when the marriage fails, the wife suddenly realizes that her faith in the guy's abilities was misplaced... except when she is the one that intentionally makes the break, of course.
