I dislike my stepmom...

Not a parent, just a 19 year old In need of advice. Is it bad that I stopped visiting my dad because I really don’t like my stepmom? I like my dad, but I want nothing to do with my stepmom and half siblings. I fee bad but at the same time I really don’t. He probably doesn’t care that I stopped visiting, but I kind of feel bad because he is my father after all. Should I try to work things out? If you were my father, would you be offended if I didn’t want to visit you anymore ? Or would you understand?

**the reason I dislike my stepmom is because when I was younger, she always made me feel like i wasn’t part of the family. I was always excluded from family vacations/events and I always felt like a stranger in my dad’s house. My dad used to stick up for me, but it never really worked. My stepmom always had the final say and I just don’t want her in my life. And I was never close to my half siblings because I was always excluded. Our relationship is non existent, I unfortunately feel no love for them. It’s sad but true
