I went through something very similar a few years ago, I'm not sure if it's helpful but happy to share.
It took us a long time and a few miscarriages before we conceived DS1 and we'd spoken about having a second so I had my coil removed on the basis that we wouldn't actively try (tracking ovulation etc) but wouldn't prevent either and let nature take it's course. I think we both thought it may take forever and may not even happen at all.
Anyway, I fell pregnant within 2 months and DH panicked. He said that, on reflection, he wasn't ready, he'd looked at the finances, we couldn't afford it (I know right
) and wanted me to have an abortion. I almost went through with it but just couldn't and told him I'd be having the baby with or without him and, if he was going to stay, we had a lot of work to do on our relationship.
Both the marriage and the pregnancy were difficult over the following months but we talked a lot, worked at it and really made the effort to understand each other's position.
By the time DS2 was born we were in a much better place (he realised he'd been a dick), he cried at the birth and fell in love instantly - he's been a fantastic husband and father to our two sons ever since.
I'm not saying everyone is the same and certainly can't speak for you or your DP but it's going to be a tough slog either way, whether you do it together or apart. The others are right though, it's YOUR decision and you have to take care of you first. You'll know in your heart what feels right
