'I'm single now but I would advise any woman to go and do it alone rather than miss out totally.'
I get branded a man-hater often, and yet I still advice the vast majority of women in their 30s who come on here posting about how they've been in a long-term relationship and the guy tells them he doesn't want to have children (when she does) to RUN. When a man tells you who he is, believe him.
There's nothing wrong with not wanting children, three of my four closest female friends in the world never did, are now in their 40s and have no regrets (they have all been sterilised, too, of their own accord). There's nothing wrong with not wanting children now.
But when you do and he/she doesn't, and you're not 25 anymore, then you need to really take a hard look about what you need and want to make you happy, because only you can make yourself happy.
If that means looking at alternatives - co-parenting with another man, be he gay or straight, egg donation (I have a good friend who wanted to procreate, but not bring up children, and is the biological parent of 4 children that she knows of), adoption, fostering, going it alone, etc. - then don't let another person stop you from taking that introspection.
For me, it meant divorce and then seeing what might happen. It was very painful.
But I know, in my heart of hearts, it would have been far more painful had I not cut my losses and had a go.
