I'm curious as to your opinion about this ongoing situation?

Father’s Day is coming up again. My father and I have never, ever been close. There has been much conflict in the relationship, and I have so many bad memories from childhood. I’ve always forced myself to send him cards/gifts on Xmas, his birthday and Father’s Day. In addition, I would call also. He never acknowledges any of my actions unless I call and ask him if he received anything from me. He never calls to ask how I’m doing. He never has. I really don’t see the point of going through the motions of acknowledging him anymore. I don’t think he really gives a sh!+….I think I should just stop reaching out. Do you think this is appropriate?
