Thanks lou riven when we decided to try for #6, I had to give up bf dd to get periods back. (*always the case for me) A month after we started trying, dh announced he'd changed his mind!! We didn't know it then but i'd already caught. I lost it Xmas eve last year. He didn't even think it mattered and moaned when I wanted to come home from his brothers christmas night cos I felt rough. He said, "look cos we have little kids we have to go home early"
I was absolutely devastated. I have 5 beautiful, healthy children and I simply couldn't get over this feeling. I pleaded, cried, tried to rationilse, I even contemplated piercing a condom!! . (I didn't do it). It was a really rough time for us, we were barely speaking as I genuinely couldn't bring myself to even look at him.
In the end, I wrote him a letter, I told him in the letter how I was genuinely worried that this would burn me up inside and I would end up resenting him, and that I was worried we wouldn't be able to get over this. I asked him to just agree to give it serious thought. He said he would and a month later he got our then 5 yr ds to present me with a bottle of gaviscon in boots telling me i'll need this soon.
I know perhaps I was a bit selfish, I know all the reasons he wanted to stop were valid but the urge to have children is so primal and strong that I truly believed those obstacles could be overcome and embraced. I just couldn't get past it and I did try, I really did.
My dh is not a man to agree just to shut me up, I know he gave it his full attention after that, and when he agreed, he agreed with his whole being and completely moved into ttc, and all that entailed. He is thrilled about this baby and we know this will be our last one and are really looking forward to it.
I know your situation is very different from the conventional but the primal need for children is still the same I believe. My heart goes out to you, it really does. I think maybe you could have a very honest talk with dh, as raw as it gets and let him know how much it means to you. I don't have the solution, I was lucky, I really really hope you will be too. 41 is not past it so you have a little time on our side too.
