I met BF through work about 4 years ago.
I have met people from the internet prior but not through dating sites (more like message boards for people with common interests, like this one). Also work, clubs, classes, and just randomly bumping into people in the supermarket.
I don't really mind being alone, so I don't think I'd ever use a dating service, but that's just me.
If something were to happen and I suddenly became single, I'd probably just spend a lot of time by myself, and not really set out to meet anyone. Virtually every guy who is remotely close to me in age is either gay, married, or in a serious relationship or I have nothing in common with them OR all of the above.
If I met someone, great. If not, I'd be pretty content spending my time doing the stuff I like to do.
But hopefully nothing will ever happen to my BF.
