Up until a few years ago that was my favorite demographic. Got too expensive and time consuming though so I'm trying my age for a year or two.
So they are giving up themselves easily, yet you have a favorite demographic? Quite clearly the reason why you can’t find someone is that you are not a person people want to be together with — maybe look for the problem in yourself first, before projecting that out to whole “demographics”.
I'm starting to see why you're having so much trouble meeting someone who you believe would stick with you through thick and thin.
