Am i wrong for not saying happy father's day?

Wassup people, For those who have a step father and your biological father, have ya'll been in this situation before, or something like it? Well fathers day just past and i been having some issues with my fathers. My biological father just started popping in my life again. He disappeared for a couple of years and now that i have graduated and im about to leave for college in august he is trying to jump back in my life which i have no problem with but my step father is another story. My biological father decided he was going to go to my graduation which was cool because he i had extra tickets. My step father heard my father was going to go and he decided he wasn't going to go because "it was hot" i got mad because when my biological father decided he wasn't going to do his part and my step father became my father there after period so i cussed him out because, i only graduate from high school once and he wanted to miss it because he wanted to be jealous of my father. I didn't wish my step father happy father's day because i was still mad at him for not going to my graduation. I just wonder was i wrong for not saying happy fathers day and not getting him something? I mean if it comes down to me being wrong im not afraid to say sorry, i like to be the bigger person. Am i wrong for not saying it though? My step father has missed every award ceremony i was in for the last 13 yrs i knew him and he feel no remorse for it at all. My Biological father has went to 3 of my award ceremonies and he just popped into my like not more than a month ago.
