Support him? What is that you are doing right now, if it isn't supporting him?!

He makes $800-1200 per month for part time work, you pay all the shared bills and his bills too, while working 60 hour weeks.

If that's not "supporting him" financially and otherwise, what else should you, could you, possibly be doing?

He's taking advantage of you, he's mooching, and this is financial abuse. You are living with his father because this is the path of least resistance, and ease, for him, and he sees no reason to change it, and he absolutely won't change it in anyway that involves more effort on his part.

Dump this loser. You can afford to make it on your own, and it will be easier when you aren't paying his rent and his car payment.
