Throwing something at you is unacceptable behavior. He is acting like a leech and a bum. Why isn't he looking for work and helping out? this has gone on for six months? I can understand if he got depressed, but then one must start to take action. Leaving you to do all the work is quite unfair, in his own mother's home. You have every right to be thinking of breaking up. How committed are you to this relationship? You can't be that committed if you're considering leaving. Do you have your own family you can lean on instead while you look for work? If I were you, I'd pack my bags and leave.
