re: Parent Problems looking for advice

Is your dad wealthy? Does he feel like people should listen to him because he has some money?

I'm sure you have pointed out specifically what he's done over and over, but has an excuse for everything. I'd have to lay it on the line and tell him no more. You've got a family to raise and you're bound not to screw it up like he did.
Much kudos to you. I've seen many a broken family lead to the next generation of a broken family.
