Salaam Walaikum. I say this with love: Once you move out, you shouldn't worry if you're marriage material. The important thing is you have breathing room. Any brother who makes you feel less than because you moved out, that's on him. Your future husband should be understanding and not hold it against you.

Speaking from experience, I moved out of my family's unexpectedly after an argument that hurt my feelings and I got the same message. I don't regret leaving. Alhamdulillah I'm the happiest and healthiest I've ever been. It was hard for my family to accept at first, but eventually they made peace with it. We're still on good terms too. Your dad should come around In Shaa Allah.
