This resonates with me a little, I am the other way round though.
I have met someone with whom I have fallen so quickly in love that I would dearly love to give him a child, but he has none and does not want any. We have only been seeing each other 10 months or so.
His actions and opinions seemed contrary to his preference for a long time so I spent some time confused. I was probably just romanticising. An incident a short while ago finally confirmed to me he definately didn't want children, but just recently he/we seem lax in the contraception area again
.
ie prepared to continue without it, just using natural withdrawal.
We are both 44 and although I know pregnancy can happen at this age despite landslide fertility, the likelihood is stacked against us in reality, isn't it? ... I have two young children already.
I'm not even that convinced I actually want a last baby, my pram obsession dictates to me I do (I have a 1950s carriage pram that needs more outings!), but the sleeplessness again doesn't appeal at all, my finances can't really cope with two let alone three children (I have been a lone parent since they were both born, their father took no interest or acceptance really), and if I analyse hard enough, I think I know that the reason is because I love him so much, I cannot think of a greater gift or way of showing that love than by creating another human with him.
Ultimately, I have to accept that he is more important to me than more children. And he is.
I already have children and am grateful for them.
But I sense a 'leaving to Fate' aspect in your situation.
