Four years ago my father passed away from brain tumors. He was 49 and I was 20. My dad and I were always very close.  A month prior to his passing I was taking care of him while my mom worked and I discovered due to his suspisious behavior that he was having and affair on my mom who he had been married to for 20 years.  I was completely shocked.  I knew i had to tell my mom but that was one of the hardest decisions ive ever had to make.  He was dying and this was the last of his time on earth, i really didnt want to hurt my mom that way.  But I told her and she was crushed.  We both continued to care for him and I realized that i had to forgive him for what he did before he died or i wouldnt be able to live with myself.  I forgave him but to this day i wonder if i made the right decision.  I made peace with my dad and told him how much I loved him before he died, i like to think it was the 28 tumors in his brain that caused him to choose to have an affair but I just dont know.  It was just his four year anniversary of his death and its still hard everyday.  In addition my mom is remarrying on Saturday so im trying to be happy for her but deep im hurting.  NOt that i dont like the guy just that its not my dad.......Any advice would be appreciated 

Thanks
