My grandfather has been a pretty selfish person all his life, with rudeness in the mix whenever he feels like it. Then he also acts normal sometimes and pretends like we're all a big happy family. I don't get it or like it.
Regardless, my parents, siblings, and grandparents actually lived in the same house for most of my life - I moved out when I was 20, which was 2ish years ago. The rest of my family still lives there. So, while my grandfather and I are not super close, we did see each other every day for like 20 years, it's not like I only saw him once or twice a year. And my family is very close other than that.
Now he says he can't go to my October wedding as he has a "conference" that day. It's not for work, he's retired; it's for some organization that he does stuff for. It's not some high-level organization or something that hinges on him being there, either.
It's fine if that's important for him, but really? It's more important than your oldest granddaughter's wedding? A wedding is a one time thing, not a yearly conference. His other grandchildren are younger and probably won't get married for at least 5 years, probably more like 10. He's in his late 70's and might not be around for those even.
I don't really know what to think or feel right now. Do I have a right to be mad/upset or is it his decision not to go if he doesn't want to? Should I try to tell him I want him to go?
