Im interested in other people's experiences and how it ended up. (Please be kind- Dh and I have both tried to be really respectful of each other over this so please don't make assumptions).
DH and I have been together 10 years, married 5. We both always wanted 2 or 3 kids, me very strongly 'think about it constantly since I was a teenager' sort of thing (which he's always known!) With him it was more of 'a family sounds nice' and he liked what he had growing up, but also didn't give it too much thought.
For some reason he seems to have found having our DS (nearly 2) really difficult. It's everything- lack of sleep, lack of personal time and I wonder if he's going through a bit of an identity thing too. He has some anxiety which hes working on, covid helping nothing. He admitted to me that he doesn't feel an urge to have any more. At first it was because he was exhausted and things were really hard so I understood why he didn't want a second right away (even though none of that put me off and never stopped being broody
). But now sleep is better and he's at nursery more, but he still wants to keep delaying ttc. He's now saying that even though things are better, he just doesn't feel the need to have another one. He's not sure he ever will. 
He knows how much I want more kids and he actually got really emotional about the whole thing today as feels bad about it but can't help how he feels. We've agreed to park the conversation for another few months and see how we both feel then.
I'm just wondering who else went through this and what you decided? I'm assuming we'll look at counselling if we can't work it out. Honestly feels gutting though. I can't imagine not even trying for another kid. Really curious to anyone else who's gone through this and how it ended up.
