Valentine's Day after syndrome

Find this very very hard to comprehend.  Before the affair my husband used to say that he didnt believe in St Valentine's day  and as a result I never got anything. I got used to it as a way of life.  When he had his affair, he went full throtle, bought expensive gifts, flowers, dined out at expensive hotels with his affair partner things he never did for me.  Now he still maintains and continues with his former tradition - I get nothing.  Its been 5 years since the affair ended but it sure hurts to know that I dont get treated well when a mistress got it all.
