I’m going to let my toxic dad become homeless

It’s not my responsibility he’s never been there for me and he’s caused so much trauma in my life. Why should I help him ? He thinks I’m going to help him but I’m just going to leave at last minuet and get the hell away from him. I don’t want him in my life. I don’t hate him. I still love him. But it’s completely unhealthy to have him in my life.
