Very interesting thread! ^
I've been pondering about the same subject as the OP. In fact, I feel like I'm sort of in the same boat: 25, single, been independent for years, have a very stable job, and pursuing a professional degree at the same time. Dated somebody for 2+ years but didn't work out due to distance. And like the OP, I tend to avoid gay bars.
Unlike the OP though, I know exactly why I haven't met anyone. I juggle between working and going to grad school full-time. On the weekends, I do one thing that I absolutely love doing: traveling. I do mileage runs, mattress runs, quick coast-to-coast weekend getaways, etc.
That said, do I want to meet someone? I do. I just have to admit that I haven't put enough effort into it.
