Think not at the personal level, but the population level here. Yes, you specifically may be just as likely to leave a marriage with a bum who never lifts a finger as a boyfriend with the same fault, but that isn’t true for the broader population. The paperwork may be an easy detail for you, and paying any lawyers fees may be easy for you.
As filmore points out and **kayaker **confirms, marriage is explicitly a burden to get out of, that leads to more misery-years for both parties involved when it’s bad. Which happens 40%-70% of the time. And this barrier exists for a lot of people at the population level. Therefore, marriage is responsible for many millions of misery-years in people that would otherwise have broken up earlier if not for the barrier, expense, and complication of dissolving the marriage.
Again, I’m making a population-level argument that marriage introduces more misery-years for both the spouses and children than would exist without it.
I actually disagree that it would not change the calculus of splitting being better than staying, precisely because it is meant to. Per above, maybe you aren’t influenced by these things, but at the population level many millions of people are. And the large portion of those that stayed in miserable, doomed marriages another few years because it was difficult inflicted those misery-years on themselves and their children precisely because marriage is more difficult to get out of.
So what happens in the 40% - 70% of the time that the marriage fails or is miserable? You think that’s better for the kids?
I don’t know what percentage of divorces end amicably, but I doubt it’s much larger than the percentage of LTR’s that end amicably, and would in fact bet the opposite way. So in this majority-of-the-time failure case, how exactly are the kids better off because it was a marriage that failed rather than an LTR? The kids will have just as much additional family with a marriage as an LTR.
People are probably just as likely to cut off all contact in either situation, and I would argue more likely in the divorce event, because of additional acrimony from the whole legal and financial morass that comes from the divorce process.
