Indeed. I know people in their 40s who are still angry and bitter about parents’ divorces that happened 25+ years ago.
When people dont have skills to deal with relationships properly, thats what happens when life stresses occur.
Fact is people tend to mimic their parents, its what they see and hear, and usually see and hear again and again. A small number see and decide to reject whzt their parents do because they see it doesnt work and they dont want to be like that - but thats not the majority. Most do because its whzt they learned and think is normal. You get two screamers and you’ll eventually get divorce. You get a cheater in there because mom and/or dad did it, and you get divorce. You get a selfish gaslighter you get divorce. You get a marriage of convenience, or because a woman wants to stop working, or just want a baby because time is running out and they need a donor, you get a divorce.
