I agree with Saffie. I have tried to follow these advices that I got here and it's working. When I go back to my distance in my bad days it has not been very helpful. Had a small consequence of one of my bad days last night.
I cannot say for sure because I do not know you husband. But I can say that if he likes to cook and was making a big dinner for his parents he was probably happy. I know that because I love cooking and just do planned meals when I am truly in a good day. And it's likely he is happy because you are trying to work things out.
Why don't you take this his cooking as something to bond on? May be tell him you miss his cooking and you'd like to work together with him on planning a nice meal for when he returns...
