Interesting story. I'm a 50+ long-time married man and none of the other guys I know and am friends with fit into what you described here.
We met our spouses pre-Internet and I guess when a woman tells me "All the good guys are taken," this must be what she means.
I have developed a close relationship with a very beautiful widow who tells me this frequently and I can't stand it that guys she meets on these apps expect this amazing woman to put out after a dinner out and a few drinks.
