Don't understand relationship with my mother
I am the youngest of 3 children. Currently my mother lives with me as my husband is travelling most of the time and also my mother used to live with my older brother and then because my sister in law and her couldn't get along she basically moved out of their house and came to live with me. I am currently going to school full time and welcomed her help with my two kids. Everything was working fine until my school schedule became really hectic and so I am away from home till sometimes 8 at night. She cooks and takes care of the house and is home for when the kids come home. Kids go to school themselves and she supervises them and feeds them once they are back from school. As I have become more busy, I feel like my mother is becoming more demanding. Like she feel like I should be doing things for her even when I have hardly any time for myself or for my kids. Even though she lives with me she does not pay for any utilities so I feel like it is a mutual thing where she stays with me and takes care of my kids. But lately I feel like she is becoming more resentful and becoming more controlling in terms of doing whatever she wants in the house and expecting more from me when I don't have any time for myself.
