Agree with ovenchips OP, we can only second guess what the answer is...so talk to your husband.
There's probably not a quick, simple answer..but there likely will be an answer. One that you reach together, when you both feel like your deep emotions are being listened to by the other.
It's not just about finding the perfect answer, it's about make each other feel listened to, respected and able to express their own true emotions at each step.
If he is compromising, he will generally listen to you when you have a reasonable conversation about it and be able to at least start to talk about how he is feeling/what he wants to do/why he thinks his way will work out for the best. He might get a bit frustrated or upset at times, but that just shows he is emotionally engaged with what is going on. He might find it difficult to express himself depending on how much experience he has about talking about things that are really going on rather than hypothetically, but he will at least try and stumble through it as best he can.
If he is checking out he'll fob you off with any old nonsense.
TBH, if his emotional response to the situation of having a child is "must provide for family, must provide for family, must work, must protect" then my guess is it's more likely to be compromise than checking out.
DH went into "must work, must provide" overdrive when I was ill and unable to work for a couple of years. It was a bit tough to deal with emotionally as he was stressed and worried a lot as he was desperate not to let me down. Would rather have dealt with that though than a bloke who wasn't prepared to stick by someone ill.
