I'm in the same boat as you Zeta. But we now both mock marriage in the belief it's become a farce - she's happy to be kept on simmer and is a refreshing contrast to the highly strung neurotic nutters out there that must conform to the trappings of society and then bounce on to the next latest fad.
If the time comes, then I will take the next step and give her what she deserves - if she's silly enough to have me. But by then marriage may be diluted even more so, which will totally stop me in my tracks.
