Hindsight Is 20-20
I got married when I was young and stupid. Somehow we never talked about what we were looking for in a marriage. We just assumed we were assuming the same things.
He wanted romance, dates, and ...yaknow, a lifelong relationship. I figured that mushy stuff fizzles after a year or 2 and you end up with a roommate, a co-parent, and an automatic date for social functions. I figured we were both pretty easy-going and flexible, and we could manage a harmonious, drama-free marriage. I wasn't head over heels for the guy, but I didn't think that was terribly important.
On the bright side, since we're both pretty easy-going and flexible, we managed to have a more or less civil divorce.
But I just think....if we'd had that one simple conversation about expectations before we got married, we'd have realized we were thinking completely different things and we could have called the wedding off. We wouldn't have bought a house together. We wouldn't have had a child together. We wouldn't have needed official documents to break up.
