I'm in my late forties, and single by choice. That's the way I like it. There is a lady I do see somewhat regularly, but I have no interest in either marriage nor co-habitation. Marriage has just never appealed to me, and I've never been interested in being a father either. I've done the living together routine for a few years, but much prefer living by myself in my own place. In part, I think it's just because I cannot get motivated to make the inevitable compromises that sharing a living space with someone entails. Just the way I roll, I guess.
If you want a realtionship, go for it. But don't ever apologize to society if you choose to remain single - though some people seem to want to make you feel you need to - never understood that
