Finn is in a motorcycle gang. He likes fast ride and women. He never was good at those stuff to be with some girl longer than a few days. He wanted just have fun with you but he can't get rid of you. You call it relationship and for him you are just a thing. Not his girlfriend, just someone he likes, a little bit. He isn't used to be in relationship so he wants to get rid of you. He wants to, but he can't. He started to feel too much for you and he hates it.
