Hi, if you cook a nice dinner every SUnday for the parents, and don't resent it that much, just do the same one you would normally do and be a nice human(like usual) on that Sunday. The man has got to eat, and you are not being an enabler by feeding the family. You are are the same sweetie you always are. I hope the partner contributes to the dinner prep! Tell the bro to set the darn table. You don't need to go any more out of your way than you normally do(which seems like plenty already!)for this guy. Or anyone that is not your obligation. I am married and I would not support that kind of thing in a relative I loved. If you miss thanksgiving cause you are in prison, well that is one of the consequences of his actions, just like the last year and a half and the legal bills I hope he is paying till he's dead. You are not responsible for HIS consequences.
