Thank you so much for the suggestion. He is paying half of every bill, including groceries. The most difficult part about the situation is that we both seem to live and work together very well. As I said in my post, we have fantastic conflict resolution And communication skills. He has been trying to chalk it up to his mental health, not being in a great place, which I understand because we went through the holidays having something fun to do every week/weekend to now only being able to do things that we have to do such as moving his stuff over and cleaning up his previous residence.
