Living with in laws

Hi mumss, may I ask how do you deal with your feeling when you stay with your in laws ? I have a very hard time right now as my mother in law would never respect my decision against anything related to my children. She will take one step ahead of me , when i say no , she will just do it . She’ll do anything that i said No when i wasn’t around. And i feel very sian because like my decision means nothing. I have stay with them for 5 years, and there’s still 5 years to go . Feel so tired and suffocating. I dont wanna speak to her but i got no choice since we are living together and she always try to get involved in my kids activities. Im glad that my children gets along with them, its just that in some circumstances i need my own life too. I wanna do things in my own way but i got no chance for now
