Most Helpful Guy
Being someone with similar habits that I still have after a breakup from 2008, my opinion is that he may be feeling lost and depressed. Filling the hole left by the broken relationship with whatever he can.. he probably keeps the basement dimly lit because sunlight does not make him feel better. Since I'm still like this, I don't know what kind of advice to give you. Also for whatever reason though, he may feel betrayed or just downright in adequate as partner.. If you were at fault for anything that caused you guys to break up, and you're actually sorry, try apologizing to him. This probably won't fix anything but, ya never know, it just might.

I was in that exact situation. I had to live with him for sometime after I broke up with him. I ended up moving out of state. I would have been happy as hell if he kept to himself when we lived together and instead I got out of the house as much as I could or he would be gone all day. I'd say don't worry about it and don't try to patch things up cause from the sounds of it, he's not trying to change. You can't make a man change even by breaking up with him. He has to want to change. Try to come up with a way to either move out or have him move out and move on girl.
