When we talk about monster mothers-in-law, we usually see a judgmental Karen who feels entitled to boss you around just like their kin. This MIL, however, took it a step further and tried to steal her daughter-in-law's house from her! 

Just imagine coming home from a nice vacation with your loving husband to find that his entitled mother has moved completely into your house. That's right, your house. You own it. That is what happened to this unsuspecting wife. 

She inherited her home from her grandfather and moved in with her husband, whom she thought she could trust! It turns out that he had given a key to his mother who was constantly going into their home while they were away. Once they were gone for over a week for vacation, she took that as an opportunity to move fully in. 

When this trusting wife returned home, she found her mother-in-law wearing her nightgown asleep in her bed. She had also gone so far as to pack up a bunch of the wife's stuff in boxes and put it in the garage…

  • When the wife tried to confront the mother-in-law, the monster-in-law replied with harsh words, saying that if she had been around, her son would have “never” married her and that her son was raised to choose his mother before anyone else. This left the wife flabbergasted. 

    She marched to her husband and demanded an explanation. He said that he gave his mother a key months ago and he was going to tell her, but he thought that she would just “come around” to the idea eventually, so he was letting it play out. She could not believe it, she was fuming. The husband, aka mama's boy, expectedly tried to gaslight her into thinking she was overreacting, but she was past the point of caring what he thought. They had invaded her home. 

    So when her MIL was at church the next morning, and her husband at the gym, she packed all of their stuff, put it on the porch, and then proceeded to have all of the locks changed, including the garage. 

  • "AITA for changing the locks after my MIL broke her lease to move into MY inherited house, slept in my bed, boxed my clothes, and my husband said I'd 'come around'?"

  • Not the guest bed. Mine. And she'd thrown half my clothes into boxes in the garage.

  • There was a note on the kitchen counter in her handwriting that said "Finally getting this house organized properly!" I woke her up and she acted like I was being rude.

  • Said "your husband gave me a key months ago, I can come here whenever I want." I told her to get out of my house.

  • She laughed in my face and said "this is my son's house and he'd never choose you over me." My husband was still unloading the car from our trip.

  • When I dragged him inside he looked uncomfortable but not surprised. Turns out he gave her a key six months ago for "emergencies" and she'd been letting herself in while we were at work.

  • Going through our mail. Rearranging stuff. She decided our vacation was her chance to just move in.

  • I asked him straight up, did you know she was planning this. He wouldn't look at me.

  • I gave her two hours to pack her shit and leave. She refused. Said she already broke her apartment lease and had nowhere to go.

  • My husband mumbled something about how we should all calm down and figure this out. I told him right then, choose.

  • Me or her. He said I was being dramatic and his mom was going through a hard time financially.

  • I said that's not my problem when she literally stole my bed and boxed up my stuff without asking.
    via KINOH1441728
  • She got in my face. Called me a selfish brat who doesn't understand family. Said she raised her son better than to abandon his mother for "some woman." He just stood there saying nothing.

  • I grabbed my purse and left. Stayed at my friend's place. Next morning I called a locksmith and had every single lock changed while she was at church.

  • I knew she went to the 10am service every Sunday so I had three hours. Piled all her crap on the front porch.
    via KINOH1441728
  • Changed the garage code too. My husband was at the gym and started blowing up my phone when he couldn't get inside.
    via KINOH1441728
  • I told him to come get his mother's stuff and figure out where they're both staying because neither of them are coming back in.
    via KINOH1441728
  • He showed up with her an hour later. She was screaming on my lawn about how I can't do this, threatening to call the cops.
    via KINOH1441728
  • I said go ahead. The house is in my name only. I inherited it from my grandfather.
    via KINOH1441728
  • She has zero legal right to be here. Police came. Told her she was trespassing and I had every right to keep her out.

  • Of course, when the MIL and husband came back, they were furious! They wanted back into “their” house, but the fact of the matter was, it was not their house. The wife owned the home, it was under her name alone, and they could do nothing about it. 

    They called the cops, and they told them the same thing. Who's being the overdramatic ones now?

    Now, that side of the family is constantly reaching out to her, calling her names, and trying to convince her she's being heartless. But it's easy for everyone online to see that it was the MIL and husband who were very much in the wrong. She dodged a very fast object coming straight for her house, if you ask us. 

  • She cried and said she's homeless now. The officer suggested a shelter. She completely lost it.
    via KINOH1441728
  • My husband tried guilting me. Said I'm cruel and heartless. I reminded him he let his mother move into our house without telling me, sleep in our bed, and go through our personal stuff.
    via KINOH1441728
  • He said he thought I'd "come around once I got used to the idea." That was four days ago.
    via KINOH1441728
  • She's been sleeping in her car in the church parking lot. My husband is at his brother's.
    via KINOH1441728
  • His whole family is calling me heartless. Saying I threw an elderly woman onto the street over a misunderstanding.
    via KINOH1441728
  • But it wasn't a misunderstanding. She moved into my house without permission, threw out my belongings, and told me to my face I have no say in my own home.
    via KINOH1441728
  • My husband helped her do it. His sister sent this long text about how family takes care of each other and I'm destroying their family over pride.
    via KINOH1441728
  • But I'm the one whose home got invaded. Whose husband picked his mother over basic respect.

  • Am I the asshole for changing the locks and making her homeless? with ALL UPDATES
