By the time you reach fifty and have never married you realize that the need to do so is long past. By that time you've either learned other means to get the same thing without marriage or you're just such a wimp that a wife now is just going to brow beat you to death for the rest of your life, and who wants that? Marriage is an institution that one eventually learns is far over rated to be more than it really is.
By fifty most unmarried men have long ago stopped being mommy's little boy turned wife's devoted servant. For those older and married they eventually realize that life without their wives is too scary to contemplate so bow to the master of the pitiful life they never lived. Sad suckers, one and all.
Apparently, there are exceptions to all that.
I divorced my first wife when I was 26, maybe 27, and stayed single until just about 2 1/2 years ago. I'm 68.
I liked being single ok until I was about 35, then I loved it. Totally loved it! The kids were all school aged (single dad here) and they liked to travel and go hiking, fishing, and camping and stuff. They were funny and interesting and maddening and loads of fun. And, of course, I dated, and was in a few relationships, some for as long as 3 years, I'd say.
Before I knew it I was a single grampa living alone in a small apartment, and the grandkids came for weekends, except over school vacation when they stayed for weeks. We pitched tents in the living room, had some neighbor kids over for movies and popcorn, and generally had some really good times.
Then I retired and got a foster-parent license through Child Protective Services, and did foster-parenting for a few years. I still dated a bit...sort of...now and then, when I had time.
Then I met Michelle. We started dating when covid was officially an epidemic, and we took it kinda slow for a few weeks or so. The grandkids were still coming over about every other weekend, but now they took turns...one at a time...and Michelle started staying with me most weekdays.
Before I knew it, Meesh and I were married, and I love it. Totally love it!
