Rather than focus on what your H is doing and trying to figure him out why don't you tell us about your history class. What will you make for dinner tonight? What can you see sitting out in your yard today on a nice day?
Your H is going to do whatever he is going to do. That is a given. It honestly does not matter if he is having a mlc or is a walkway or is Bat guano crazy. What matters is that you have to find a way to refocus.

Look not mournfully into the past. It comes not back again. Wisely improve the present. It is thine. Go forth to meet the shadowy future, without fear. {Henry Wadsworth Longfellow}
