Relationships change, over time. We need to change, and adapt.

When we're young, things are quite different, from when we get older.

Lot of "not-easy" stuff, involved in long, committed relationships.

Been married for over 30 years. Lots of rough spots, along the way.

We're doing OK, nowadays.

I remember that a bunch of siblings were criticizing their parent's relationship.

In fact, their parents were married for decades, and truly did the "Until death do you part" thing.

There was definitely some dysfunctionality, there, but they stuck out some really difficult times.

I have also seen relationships that were "the match made in heaven," fall apart, fairly quickly (in one case, a couple of weeks after a big wedding).

It's always easy to find fault with people that we can't relate to, or give advice that works for us, but won't, for them.
