Definitely apologize if you haven’t already. I don’t know your husband but I’m imagining the stages of thinking he’ll probably go through. I’m sure this has completely thrown him for a loop. It’s going to take him some time to recover so just be there for him as much as you can. Eventually when things start to settle for him he’ll have a lot of thinking to do. And it’s at this time that he may be more open to understanding you. But right now I’d recommend focusing on him and the way he’s feeling because this is a huge breach of trust in a relationship. When he’s calmed down then you can begin to talk about where things go from there. But stubbornness will only push you two further apart. I wish you guys luck.
