I remember I used to give this guy who I worked with at a meat packing plant rides to and from work. After we became somewhat acquainted and he discovered I'd never had any kind of relationship experience, he started always telling me, whenever the topic arose: "Single moms are so horny, man!"
Nice guy; I think he was trying to let me benefit from his years of invaluable experience. Everyone's got their niche, I guess!
Still, I don't like the idea of perceiving single moms as desperate and an "easy win," nor do I like the idea of being an object of desperation, or a kind of "ah, whatever..." partner. Outside of that, it's probably all good, so long as the topic of single motherhood is just an incidental facet of how we get to know each other. If it came to raising kids, I might frankly need to learn how to do it, first. Even then, I might run into the only-so-far-aspie-relationship wall. Who knows.
