I think you have to have a lot of soul-searching conversations with your husband.
The reality is, even if you’re happy in your relationship now - it’s very likely that having a baby would put intolerable strain on it if your husband isn’t on board. Having a baby sucks everything from you to begin with, and while it does absolutely get easier you have to survive those first few months of adjusting to the fact that you and your spouse are no longer one another’s first priority.
If your husband is ambivalent about having a baby, he will likely be resentful of the fact that you can’t / don’t put him first any more. And nothing can prepare you for how much work it is, and how much you will resent your partner if he doesn’t pull his weight and be an equal parent.
I say this because my husband is an incredibly committed and doting father, who easily does his share without prompting, and we have still had moments of resentment and difficulty. Luckily only moments, but I can see just how awful it would be if he didn’t pull his weight.
There’s absolutely nothing wrong with deciding children aren’t for you. It doesn’t make you less of a family, it doesn’t make you unfulfilled or mean your life is empty. You and your husband are complete individuals with purpose and value regardless of whether or not you have children.
Equally, there’s nothing wrong with you deciding you do want children. They can be a source of enormous love, joy and fulfilment. It’s absolutely ok to want that.
But you need lots of open, honest and deep conversations with your husband. Is he reluctant because of the miscarriage, or because of the whole idea of children? Does he want them for himself, or to please you? Would he do his share, willingly and freely and because he knows it’s his responsibility to his child, and not as a favour to you? Would he see the work as your job because you were the one who wanted a baby? Would he hold it over you when times get rough because this was your choice not his? Etc etc. Once you’ve really delved into this, you’ll hopefully be in a better position to decide what’s right for the both of you.
