Why is he single guy coming home way before the married man with three kids. Again...trying to prove something. And I don't know why? I never put up a fight, I never voiced anything bout when I would like him home.
Maybe you should be a little tougher with him. Sometimes a WAS can be like a rebellious teen- teens push and push and push the boundaries to see what they can get away with. And if their parent knocks them back into place, they blow up in a dramatic fashion externally while internally they are joyful over the fact that someone loves them enough to enforce boundaries with them. Remember that DB'ing is experimentation- try different things and keep doing what works and discard what doesn't work. Don't be afraid to try something different.
