Hi Sona, sorry to hear you are having a bad time with your MIL. I'm not married but I have seen my friends and their MIL and they say it's worse when you have kids..
How you guys have survived living under the same roof is amazing.. I love my family but I love them more that we are an ocean apart LOL.. I can't imagine living with them.. Too many adults with different set of rules and how you do things etc.. under one roof is a bomb ready to exploded even if you guys get along and have a great relationship..
hang in there it will get better
HUGS
