I have learned the VERY hard way that not dealing with the grief really is not the way to go. It was a terrible struggle for me that really took a toll on my physical and emotional health. I tried to push the grief aside for a LONG time and it resulted in terrible anxiety/panic attacks. However dealing with the grief was equally as hard but something I found to be necessary to get on the path of healing.
It is a balance and there is no formula that is 'right' or 'wrong'. I really do feel that is why forums such as this are such a tremendous resource.
My H also thought after some time passed he and I would be 'pals' and I do think it is has been rather earth shattering to him that a friendship at this time does not exist between us. In the message he sent last week he really expressed his shock that I am no longer there for him. He sent me a terribly mean message shortly after Thanksgiving filled with his displeasure that I did not text him and wish him a happy holiday. He went on and on about how hurt HIS feelings were.
I am sure it is difficult to have your in-laws around but I think you are doing great!
