WIBTAH If I don’t call my grandpa on his birthday?
Today is my paternal grandpa’s birthday. Growing up I was really close with him, he lived with us for most of my childhood and he was always funny and nice. We frequently went on walks and I spent a decent amount of time with him. Last year he had a heart attack and moved to another state with more of my dad’s side of the family. Before he moved back my mom was saying bye to him because his health was still not great and was talking about how she would miss him. They were hugging and my mom thought he was going in for a cheek kiss (which was something he normally did) but instead he purposely kissed her on the lips and put his tongue in her mouth. My mom said she froze and didn’t know what to do and luckily my brother walked in pretty quickly and my grandpa stopped. My mom was extremely upset by it because she was a victim sexual abuse when she was younger and It brought back a lot of feelings. She feels really betrayed by him because she saw him like a father. He’s never done anything to any of us before and it was extremely weird. He has still been of sound mind and so it doesn’t make any sense to us why he would have done that. My brother, father, and the rest do our family don’t know about it, only me and some of my mom’s friends. My parents have been separated for about 8 years but they’re on good terms and talk often because my brother lives with my dad. I’m really torn if I should call my grandpa to tell him happy birthday. I really haven’t talked to him much and his health I’m sure is still declining. I mainly feel guilty because my dad, brother, and aunts on that side have no idea why I wouldn’t want to call him and if it was brought up I still wouldn’t be able to tell them why because my mom doesn’t want them to know. I feel like I should call and just try to make it quick. Would I be the asshole if I didn’t call or if I did call, making it short?
