I could be wrong here, but it sounds like the OP has been very ill, and perhaps has not been able to be her DH's constant Maid,Mother&Mistress.
I can say that my DH is one of those who never really appreciated all that I did for him, and for our marriage. I am truly not putting him down and male-bashing. That is simply just the way it is. His mom always had taken care of eveything. And, all of this was simply not in his conscience reality. I think that this is still very common in guys. Like the one other poster said... Did I go around demanding to be thanked and having my ego stroked??? Well, I would have been in trouble if I had, because a 'Thank You' would have been months and years in coming. The very thought of hearing my DH say 'Thank You, I appreciate that' for every time I washed and folded his underwear and socks.
Unless the OP is being demanding and critical of the things he is doing... which I do not get the feeling is the case, Then maybe her DH may need to adjust his expectations and get over it. ????
Just from the tidbits that the OP has posted, it sounds like these two know that they love and appreciate each other. To me, it sounds like the DH may be a bit 'down' about how things have been going. And his fragile immature male-ego needs stroking. However, In reality, there are times in life when it is not about acting like two love-stricken teenagers.
I am all for showing love and appreciation!!!!

However, this is something that should not be constantly needed or demanded. Just a word of warning... An ego serves no real purpose. And it seems that the more you feed them, the bigger they get.
