My mil after my FIL passed away

It’s been 6 months since my father in law passed away I was always attached with him so can understand totally.. but it’s been 6months she is sleeping in our room. I don’t know if I am wrong or right in this but this is quite weird to me.. first few months I was fine with it but now my husband says give her a years time.. I mean what the f me and my husband sleep on the mattress on the floor and she sleeps on the bed claiming she is afraid..anytime we go out somewhere she will cry in front of us making my husband feel guilty.. she is completely fine when we take her out to shop or holiday.. she wants to holiday almost every month. We have been trying for a baby since a year now but because of her we are not getting private time .. whenever my husband wants to get out of his emotional state of losing his father ..she pulls him back. I can understand her loss is big but how is that her emotions are different in front of her daughter and different in front of us .. I have started feeling sad and depressed because this is such a sensitive topic .. I don’t know what to do.. right now I hate myself and everyone around me.
