I am 50, never married. Where I have been, is clear to any woman I encounter, as I was busy building multiple careers.
What you say is confined to the ugly men, the fat men, and the losers, for whom no explanation is necessary.
Every woman I meet assumes that she is going to be the one special person who will change me into relationship material.
It generally takes them about a month to determine that I like my life just the way it is, and they move on in search of easier prey.
Whatever you say big boy.
