Is it normal that i hate holidays now ?

My parents are each twice divorced. Every time I'd get comfy with their newest family they'd cheat or be jerks and another divorce would happen followed by mom or dad telling me we aren't going to see them anymore, right ????? I'm so tired of my parents destroying the lives of others (and me) and not even caring about repercussions. The only other people in my family that I had that were "secure" have now all died . As a result I hate Thanksgiving & Christmas since they've both been revoked and the participating parties swapped out so many times. It's not easy to switch off and on emotionally like that. My stupid dad gets mad at me because I don't WANT to go see and maybe start to like wifey #3 only to have him then dump her (again) for another co-worker....etc. I just hide out and try to avoid everyone. It's sad but so is what's happened to my family. I'm female, 40 & an only child.
