My best friends Mum hates me?

My best friend used to be the perfect, ideal kid. Then she moved schools and we became friends. After we became friends we started doing stupid teenager stuff (nothing out of the ordinary, drinking, smoking, sex, weed). Neither of us pressured each other to do anything it just escalated and we would want to do this stupid/crazy stuff with one another, we had fun. But now her Mum thinks I am the bad influence of my friend and she HATES me. Today she would not let me in her car. She really despises me. But I am moving states in less than three months and it is unlikely that I will see my friend for a very long time (it's not like her Mum is going to let her come visit me), so I want to spend as much time with her as possible. My friend says that she can convince her Mum to let me spend the night and stuff at her house, which I obviously really want to do, as we cannot stay at my house (it's being renovated). My question is what would you do? Would you go over to her house knowing you are unwelcome?
