I am so, so sorry for your loss. I have also been where you are now, I lost 4 babies over 3 years trying to have a second child (after nearly miscarrying our DD18). It is such a difficult journey and can have devastating effects on your marriage and family.
Please keep communicating, even if at the moment that means you sit and cry together, and you will eventually get through it.
Sending you prayers, and if it helps, please do pm me and chat.
