I have decided I'm gonna cut ties with my father.
What are you going to say to your father when you bring it up?
Dad, I'm tired of your shit. You should've loved me like other fathers love their son.
I'm sorry you are feeling that way and it is okay to want to be only around people who don't cause you pain. Your father may have a lot of making up to do but hopefully in time you can forgive him.
I'm only concerned about myself.
At the end of the day, making sure you are happy is the most important thing. Hopefully this will make you happier and will cause your dad to rethink how he acts. Maybe in the future you two can have a better relationship.
