I really feel uncomfortable around my dad and I don't know why

I (20f) feel so very uncomfortable around my father. And I have for a long time, say, since I was 12 or 13? Maybe sooner but that's when I started to notice it. I've never been able to pinpoint a reason, either. I just do.

I don't know if it's emotional unavailability from his end, he's never been somebody I could go to about anything. He spent a lot of my life telling me he never wanted kids too, had them for my mom and their marriage. And a few times has asked me, "hey, didn't you ever try and stop your mom from cheating?"

Maybe it's the fact that he made sexual jokes and comments about women around me for literally my whole life. And that was a point of anxiety for me as a kid but I didn't think it still bothered me.

I just don't know what else it could be. It's this deep rooted, just extreme sense of uneasiness and some anxiety around him. I try to avoid being alone around him. There's not much to be said, anyway. He's awful to talk to.

But I feel guilty bc he does help me with money and stuff. I don't struggle like that. So I feel bad for being uncomfortable
