Fathers Day question.. didn't get card or gift for my husband?

My husband has a history of infidelity. I know this has nothing to do with the children but recently I found out about some activity of cybersexting. Just want to know if any women have felt the same way. I have a hard time feeling generous towards him and he tries to make me feel guilty. I feel he doesnt deserve recognition from me because he is lying and secretive. Should you observe fathers day for your husband even though he has been lying to you? Am I suppose to pretend that he is a good and loving person/father? I am not saying this guy has been horrible in all aspects of his life, I guess I really want to hear from those of you who have a similar life experience.
