I'm an astoundingly selfish person, and unapologetic about it. Makes for having relationships, romantic or otherwise, pretty much impossible.

I'm middle aged, dated, had relationships in the past, etc., and honestly just don't have the drive to make relationships work. I do the bare minimum to keep my professional relationships in tact, which honestly is exhausting enough, and otherwise just keep to myself. It's so much easier than when I was trying so hard to pretend I was interested in where another person was coming from or what they were going through. Now at least that effort ends after I clock out for the day, and there's less socializing where I work, so there's less of those kinds of social expectations overall.
