I’ve been dealing with my sister-in-law (let’s call her “Lucifer”) for years, and at this point I don’t want petty revenge—I want the truth about her to come out in a way that actually sticks.
Back in 2019, I moved in with my now husband and his parents. In 2020, Lucifer moved back in after blowing up her own relationship. While we were at a family reunion, she called my husband claiming her boyfriend was beating her. He told her to call the police. She did—and then called back furious saying she lied and was “just mad.” That resulted in her boyfriend getting a warrant, their breakup, and her moving back home.
At first things were fine. My husband and I paid rent and helped maintain the house. His parents are both deaf, his father is blind, and they’re retired—so we tried to help however we could.
Then my husband sat down with them to go over finances… and realized Lucifer was draining their money.
She quit her job shortly after moving in and paid for nothing. Meanwhile, their parents covered everything for her—phone, gas, food, alcohol, weed, hobbies—you name it.
When my husband suggested they cut her off financially, she overheard (she constantly eavesdrops) and completely lost it. She got in his face, screamed, shoved him, and shut down the conversation.
That was just the beginning.
From there, it escalated into daily harassment:
Unplugging Alexa devices (which her blind father relied on) because she thought the government was listening
Overfeeding our cats and blaming it on their autistic sibling
Spitting in my husband’s face
Letting her dog pee in the same spot daily and refusing to clean it
Messing with my laundry—taking my clean wet clothes out mid-cycle, mixing them with dirty clothes, and locking me out of finishing
Lying to her parents in ASL (which I’m not fluent in) so they couldn’t understand what was actually happening
She would glare at us, flip us off, provoke her dogs to bark at us, and cause scenes in front of guests.
Then she met a guy and moved him in after two weeks. He eventually quit his job too.
One day during an argument (again triggered by her eavesdropping), her boyfriend came up behind my husband and slammed him to the ground. Cops were called, but nothing came of it.
I later got pregnant, and we tried to stick it out for financial reasons… until she crossed a line I can’t forget.
She somehow got my father’s address—someone she has NEVER met—and sent him a 5-page letter full of lies. She accused my husband of abuse, painted us as horrible people, and even threatened to call CPS on my unborn child.
That was it. We moved out.
Life has been peaceful since leaving, but she didn’t stop.
She’s spent years telling her version of events to extended family. We stayed quiet out of respect for my husband’s parents—but she didn’t.
Eventually, my brother-in-law (“Patrick”) and his pregnant wife moved in despite our warnings.
It took TWO months.
Lucifer invaded their room, started “cleaning” their private space, and when confronted, she attacked Patrick—cornered him, swung at him, tackled him, and then called the police claiming HE attacked HER.
She was arrested for DV.
Months later, she assaulted her blind father. Arrested again.
Then got a DUI.
Despite all of this, she still plays the victim to the rest of the family—and we’re still painted as the bad guys because we never told our side.
We’re now no-contact, as is Patrick and his family.
Recently, we tried to do a holiday without her, and she spam-called my husband 20+ times from a blocked number making threats.
At this point, I don’t want drama—I want accountability.
I want the truth about her behavior exposed to the family, but:
I don’t want it traced back to me
I don’t want to cause more stress to his parents
I want to stay completely within legal limits
She has a small YouTube presence where she posts like she’s a normal, kind person—which makes this even more frustrating.
So Reddit… what would you do?
