Doesn't sound like a great loss to me. Of course, I'm from an era where fornication was considered wrong, and more people saved themselves for holy marriage. It was nothing like this immoral, modern free for all where people change mates like they change underwear. I guess people nowadays equate dating with sex. That's their choice, but there ARE real world repercussions for immoral behavior.
On the other hand, the guy didn't deserve this, but getting burnt isn't unexpected when one plays with fire. Exotic dancing isn't a profession like any other, and gentlemen clubs aren't really for gentlemen. That's why many exotic dancers have drug problems, prostitute themselves, etc. It's not a noble profession. It's an industry that feeds on the basest human desires.
The guy didn’t deserve it? The guy left himself open for it. He was using her. He admits he never planned to have children with her.
You reap what you sow.
