My goal was a lifelong marriage. My mentality constantly evolved toward that goal. However, my judgment was insufficient and I didn't properly recognize that sustaining the marriage was harming our kids. In an earlier time, the harm would have been much less. Kids (my generation & earlier) once had direct, relationship-level access to a number of caring, invested adults - related and not. My kids had the two of us 24/7 and that's about it. My wife and I had 10x the parenting demands (time) put upon us that my parents, grandparents-> adults through human history had.
