My Mother-in-Law Moves In with Me and Gives Her Home to Her Daughter.

My motherinlaw decided to move into my home and handed over her flat to her daughter.
My husband, François, grew up in a large family. My motherinlaw had children until her daughter was borna strange tactic, but not for me to judge.
When I got married, I thought I was lucky. François seemed responsible, brave and strong. He understood what a family was, yet he couldnt break away from his mother and sister. While the motherinlaw didnt pay much attention to her sons, she always put her daughters wellbeing first.
Chloé was ten when I met her. At first she didnt bother me, but five years later the situation worsened. She refused to study, kept odd company, and my husband had to step in to help with her education. My motherinlaw would even call in the middle of the night asking for assistance.
I hoped Chloé would grow up, marry, and everything would settle down. That never happened. When she found a boyfriend, my motherinlaw demanded that her sons contribute to the wedding because she had no money. The fiancé came from a modest background, so the newlyweds had to live with my motherinlaw.
She soon realized they were struggling to coexist, and she came up with the perfect plan: move in with us and leave the apartment to her daughter. It didnt matter that I had bought that property with my hardearned money while my husband contributed nothing. The surprising part is that he is also happy with the arrangement, claiming his mother will ease the household chores.
We have a threeroom flat, but I dont want to sacrifice comfort or share my living space. My motherinlaw is convinced we are obliged to host her because my husband, as the eldest, must care for his parents.
I love my husband and Im not considering divorce. But how do I bring this up with him? How can I explain that living with his mother feels like a nightmare? Any advice?
