I totally agree w/what Sotto has posted. In his mind, the mundane things are responsibilities that he doesn't want to deal with. Remember, they are thinking like teenagers and having to fix a towel bar is just not something he wants to deal with. So, w/that in mind, locate a good handyman and start phoning when you need something repaired.
He doesn't want to deal w/responsibilities at the moment and that's why he started venting away. Try to have a Plan B in place and don't rely on him.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
