I remember when I was in college and my wife (then girlfriend) was telling me how screwed up her family was. I said "Oh yeah? Try me". I won. I haven't spoken to my brother in 10+ years and he hasn't spoken to my parents in that long either. That is not because of me. I've attempted to reach out but stopped about 5 years ago after my son was born. The entire side of my mom's family is either a) raging alcoholics who are either in the process of dying, or dead, b) serial narcissists who have more spouses than I have dress socks, c) been incarcerated multiple times (both of her brothers - one for possession and distribution of meth, the other for shady dark web shit) or d) drug addicts (see 3)). It's kinda odd how "normal" my mom is, all things considered. The history of alcoholism that runs in my family is why I don't drink (one or two drinks per year).
I REALLY try to limit spending time with my mom's side of the family for the reasons above. They just aren't good people to be around, especially with a 5 year old in tow. My parents are fantastic folks though.
