One of the things that I noticed during my married years was just how hard it can be for a couple to meet another adult couple they can spend time with socially. There were plenty of couples we knew, but that was because I was friends with someone in that couple before they were in that relationship. Most of our friends were my friends who she met through me, or friends of hers that I met through her. There was really only one couple that we met during our entire marriage where we clicked completely and they became basically family to us.
It started when they moved into the apartment directly across from ours. Right around the time we found out we were having our first child, they found out they were expecting as well. We started out chatting about that, and then little by little realized how much we all got along, and by the time our kids were born, they were absolutely part of our lives. They live in Alabama now, and one of the strangest parts of our divorce last year was thinking about how we won't have that experience again. I'll see them, and I'm sure she'll see them, but part of what was great was the way it felt to hang out with them together, with all of the kids. It was invaluable, and I felt like a big part of what made it work was that we all understood where we were as people and as parents and as adults.
