Well, just that really.
I want another child, dh doesn't. We were always going to have 3, and now he has changed his mind.
We have 2 dds, and I love them dearly, but really, really want another. After dd2 was born, we were having a bit of a rough patch, and agreed to postpone trying for number 3. Dd2 will be 4 soon, and dh is now adamant he doesn't want anymore.
I'm not sure I can accept this (although what choice do I have?)
