Looking back I'd have to say mine was high maintenance (well, when he was home, which was as little as possible). The last year and a half was always me and the kids walking on eggshells, there were no discussions that didn't end with a snarky or nasty comment.
He is one of those people who always thinks he is right and belligerent if you probe him wrong. Just like his mother!!!! He always feels the need to win, was always the one with very little empathy for others (I am a bleeding heart, of course, the exact opposite). He is the one at work who fires people when needed because it doesn't bother him.
