Father's Day - Help!

Father's day is coming up and as much as I'd like to do something for my Son's father, he does not really deserve it. He has not done anything for my child and at this point asks about him once every 4-5 days. He does not try to learn about babies and their developmental milestones, does not bother to research things if he has additional questions or concerns and it feels like he is solely relaying on me to educate him. (Like I know everything about being a mom/parent or something. 🙄) There is a lot he does not do that I feel he should if I were in his position. Even the small things like buying diapers, wipes, formula or clothes. My son is perfectly provided for and will never go without, but the thought of him even attempting to help is not there. He doesn't pay child support either.

Am I wrong for thinking this way? Should I still do 'something' for him or at least acknowledge Father's Day? I was not granted the same courtesy with Mother's Day, my birthday or any other holidays. I tend to match effort and there is none from him.
