I moved out when I was seventeen (I'm 19 now) but I still have contact with my mom. It's different because I do not rely on her for food, money, transportation, education or housing. Our relationship has improvement much since then. She typically treats me like an adult when we talk. I've loaned her money before; I babysit occasionally; sometimes she'll ask to go to lunch or visit my university.

In regards to the difficulties you are experiencing, just keep in mind you will not have to live with your father forever.
