Ok now my dad is acting all nice, idk what to do?

I think you should leave if you want to. Your dad has no room to tell you to get a job when he doesn't have one himself. I'm guessing your source of money comes from your mom. If she cuts you off and tells you to get a job then I would do it. Since you're in College, and actualy doing something with your life, that's respectable. If your dad keeps giving you ****, I'd just go get an easy part time job and choose the hours you want to work, then he can't give you any crap
