My impression is that staying together as a couple does not correspond to the challenges themselves, but whether the very idea of breaking up is an option on the table. If it is, then some people take it. If it's not, then they will keep working at it. You must know people who were terribly suited who make it work. And there are couples who seem perfectly suited that break up. It's a mystery to everyone.
