Husband upset over my coldness to MIL

Hi friends,

I have been married for about 5 years now. My MIL stays with us. DH's father is no more. Things were all fine until my DD was born (about 2 years back). And after that my MIl became super competitive and started acting she was my DD's mother. I resisted and started taking care of her after I come home from work. (we have a maid to take care when I am at work). These tensions spilled over to the kitchen and she started a lot of passive aggressive domination and stuff.

Because of all this, the relationship with my MIL got strained. I lost my health and my peace of mind, and then after a few such incidents, MIL and I stopped talking much to each other. Its basic hello-hi and strictly business.

I spend a lot of time in our room and rarely go out. She does the same as well. This has given me peace of mind that I was missing from so many years.

All sorted out right? No! My husband is now going through a huge guilt trip about how his mother is unhappy . He has gotten extremely depressed about it and somehow wants things to magically become normal. He also says he is worried, that my limited relationship with his mother will affect our daughter. He feels his mother is 'left out' of everything. This despite her being able to spend a lot of time with my DD who is with the maid and her at home.

I think he feels responsible for his mother's happiness and feels this coldness is impacting it. The less I talk to his mother the greater my peace of mind. However, he is impractical and wants things to be all rosy. I feel lost :(
