I have nothing to add to all the wise advice on here. I guess your underlying problem is that your husband sweeps his feelings under the carpet and thinks you should do the same. Well, as you have said, he still suffers from depression even with that attitude and will oontinue to do so. You have a choice, however - get help via your GP, a private therapist or whatever, there are people out there experienced in what you are going through, and worth consulting.
I have a husband who never expresses feelings, and am not even sure he has any. If it wasn't for me he would never suggest that we arrange to see our grandchildren, he isn't that interested in them. Though he would disagree with me.
It's very hard when you can't share feelings with your husband, so you have to look to other people, and it will be worth it if you do.
Much love and luck XX
