I know I don't represent all men's POV, but you keep bring up "too nerdy to F." I don't see being too nerdy as a problem. I don't see being 42 as a problem. I don't see some of the other things ( a littler heavier than ideal) as problems.
It those things are problems for a guy, move on. He isn't the right guy for you. Eighteen year-old guys, being nerdy might be a problem for them. Mojo, this isn’t your college years, so don’t worry about what was and wasn’t when you were in college.
I am certain that I am not expressing myself adequately/accurately. I am currently experiencing no difficulties whatsoever in attracting men. I'm just sort of sickened by my success so I'm trying to be objective about it. Understand. I had no difficulty whatsoever attracting men when I was young and single. I have no difficulty whatsoever attracting men now. So...WTF went wrong in my marriage and how can I , dear Jesus Puh..leeze, stop it from ever happening again? is the issue.
