It seems that he would have to put his priorities in order and figure out what he wants to do himself.
It is acceptable for couples to have different hobbies and interests. If they always liked the same activities that would lead to boredom.
You could tell him that he ought to figure out what he wants to do and not be in this roller coaster which is unhealthy. Meanwhile, you could engage in some soul searching yourself and let him know that is what you're doing.
The two of you could also go to a couple's counselor if that is something you both want to try.
He has decided to take a week's break from me with no contact. I'm not sure if I should just move on or stay having feelings for him. He won't give me a straight answer whether he wants to try again after he feels better. I think he may be affected by his depression...should i still wait or just let go?
