2 people staying together for the sake of there kid causes more problems than if they were divorced
Well, I have frequently pondered that question, because I believe this is exactly what my parents have chosen to do.
My parents have been married for nearly nearly thirty years, and apparently, their relationship was good for quite some time. However, to put it bluntly, my mother basically got sick of letting my father control her life. That occurred roughly ten years ago, and since then, their relationship has been very marginal. They now have separate beds, and no longer travel together or go out together. Just about every evening they get into some kind of argument, usually over some very trivial matter...even something as simple as the dinner menu. The two biggest factors at play here, IMHO, are arrogance and resentment. But yet, its the very pettiness of their grievances that I feel is responsible for their decision to stick it out.
I'd like to say it doesn't get to me, but it does in inconspicuous ways. The most obvious manifestation is in how I have a very difficult time focusing on almost anything when they are nearby. In order to study, I really have to cloister myself off in my room, far away from them. Also, the situation makes me reluctant to bring friends over to the house.
I do know one couple where the situation was even worse...ironically, it was my father's father and his wife. They actually got to the point where they would pass by each other within their house without even speaking. They got so that they lived totally separate lives. Once, my grandfather brought some friends from Mexico come to stay for two weeks and never even gave fore mention to his wife. There's a lot more I could say here, but I should probably just leave it at this.
