I'd bet that the reason it's hard to find an available man who wants an LTR is because those guys spend very little time "on the market" before they're snapped up by someone.
Interesting observation. I’ve been claiming a variation of this pretty much forever and was often met by disagreement. However this is not limited to only guys, it includes women as well. My claim has long been the good ones are already taken. Good ones don’t walk away. They don’t have affairs. They don’t do all the things that put many of us here. I’ve often reported how I meet a seeming great woman only to find she’s married or in a LTR.
Of course that doesn’t mean those not taken are broken or bad. I don’t consider myself to be. But the pool of quality, available people in our 20s is far less in our 40s or 50s. That’s because the best of the pool in our 20s are still married in their 40s/50s. Add in the chance of D for second and for sure third Ms are much higher than the already crappy 50% for first Ms. And it’s not a pretty picture.
There are still good ones out there. They are just much harder to find and yes sone of them have zero interest or are too scared to take a chance on dating or an R again so they rarely if ever date. I find that constantly in my age range and could easily rattle off a dozen names of attractive, accomplished, quality woman who rarely or never date.
