I recall replying to your introductory post. And I feel as though there should be something insightful I could say about what you're experiencing with your husband since it sounds as though he & I have some things in common. The way he is relating to you now is pretty-much the way I relate to my wife. It would be far too complicated for me to explain how it is I have come to the place I'm at. But I guess I would simply suggest your husband's aloofness is likely a symptom of his depression not a sign of his love (or lack thereof) for you.
You mentioned he has started therapy. And I think that's probably a good thing because I don't know how else one gets around what your husband is experiencing. You didn't mention how old he is. If he happens to be middle age, that may be at least part of what's going on with him. But it's possible there's more...maybe even stuff from his past he's never spoken about with anyone but needs to. And then, of course, there's the problem with your parents.
I do think you're correct in terms of how you're handling your parents. There have to be boundaries in any relationship including those with parents. And if your parents simply can't or won't respect yours & your husband's boundaries, then you have to do what you have to do to protect your marriage. By the same token, though, your husband also needs to take responsibility for his feelings. Hopefully that is something he can learn to do more effectively in therapy.
I know I gave you a slew of links to articles, from PC's archives, when I replied to your introductory post. However here are links to 6 additional articles I don't think I gave you that touch upon the points I've made here:
