I think you should write a nice thought out email explaining how you feel and why you're feeling this way. Maybe also ask your husband what can you do to make things easier for him. A bit of give and take!?
I found the visa process very stressful and worrying and it was hard to switch off and find time away from all the things I needed to know, research and prepare for the application.
One of the benefits of my work is that I am finished by about 12 noon most days, this allowed me time to stay in contact with Tonet more than if I had a 9-5 job.
Something that did change during this time was my social life, I rarely went out. That was my choice though, so perhaps your husband is simply finding it difficult to balance all the things going on in his life!?
I hope things work out for you both asap!!!
