Goodness, please don't listen to the woman who is telling you that you should leave him. If you are happy and you are in a great relationship - marriage doesn't matter. If you really ask yourself and dig deep, you'll probably find the real reason why you want to be "married". For me, my long term relationship doesn't need the title "marriage", I'm not religious. You sound happy as you are, don't allow society to tell you that you are a better person if you're "married". You seem like a great pair to me!
Remember - If you leave the bird cage open, the bird is more likely to stay on the perch!
