Should I talk to my father again?

I have yet to have a real relationship with my father in over a year now. It basically all started when he tried to force me to go to counseling but a lot of stuff was built on top of that and the crack finally split. My parents divorced when I was one and I live with my mom. I used to go to my dads every weekend. I always felt he cared more about his step children and new wife more than me. He constantly made remarks like, "Move your @ss so Sherry can sit by me!" (Sherry is the code name for his wife) He was always paying everything for her kids and getting new furnerature and stuff. He dropped 2 grand on braces for his step kids but when I needed them he couldn't help my mom who didn't have the money because of her expensive monthly injections. He even bought them all new cars but still never helped with my braces. I had a lot of pent up anger over that. His wife always treats me like I'm some sort of animal. I had to sleep on the floor so I didn't get the couch dirty. She always blames anything her kids do wrong on me. Like when a plate got broke or the garage door. The thing is he always believes her over me. He let's her spend all of his money. So apparently he's always broke. Yeah...how'd he get those new couches and flat screen and again I'm back to the braces. I started showing my anger towards all of them. He eventually said I was crazy and tried to get me help and I haven't talked to him since. That's been a year. He's been trying to talk to me for the past couple of months. I talks to him once and he refused to apologize or admit his wrong doings even though I apologized. He said I need to stop being a "*****" and suck it up. I told him to get the f&@k out of my life and he's still trying to get me to come back over there. So should I forgive him?
