I had a similar thread about my biological urge and whether it ever goes away.

I still hold on to shreds of hope that DH will come around. It hurts me too much to think that this is it So until his definite no becomes an adamant no, I still talk about 'next time'.

Usually when I have a bad day with the kids or something he throws it back at me that I'd never cope with 3, so we're definitely not having another one.. other times I almost get the feeling he's entertaining the idea of 3. So I have highs and lows at the moment.

But I totally understand how you're feeling, and I think if you explain it to him the way you have here about needing to grieve the fact that there's no more babies he might understand a bit more. Try and talk to him when it's not O time tho! I think they need to understand that we have that biological urge & desire, and it's not an easy thing to overcome.

*hugs* to you.
