It’s a famous trope – the nightmare mother-in-law that always causes drama.
They’re often the butt of jokes and many Reddit rants, but is it really a fair stereotype.
According to one cunning wife, yes, they really can.
She’s taken her issues with her husband’s mum to a new level – and managed to upset her partner in the process.
It all started when the woman, 34, and her husband, 37, purchased a new home recently after a year of marriage.
As he revealed on Reddit, part of the problem stems from his mum’s nosiness – and her inability to respect boundaries.
“My mother-in-law kept pushing to get an emergency key.
“She promised that she only use it in an emergency but given the fact that she had an emergency key to our old apartment and walked in on us being intimate twice, I just couldn’t trust her,” explained the woman, adding that her husband didn’t think it was a big deal.
In a ploy to expose her, the woman sent her mother-in-law a fake key – which naturally didn’t work out well.
She explained: “Days [go] by and [at] Christmas dinner MIL angrily called me out on the fact I gave her a fake copy of the house key.
“She shamed me for doing this in front of everyone but in my [defence] I asked her how she found out and she said days ago when she came over while my husband and were out.
“I reminded her ‘Didn’t you promise you wouldn’t use it unless there’s an emergency? So you tried to get in when there was no emergency and you broke the promise you made to us?'”
This didn’t go well, as the mum promptly had a “huge meltdown” over the situation, resulting in an awkward Christmas day.
“My husband went off on me in the car and said I lied and manipulated and humiliated and exposed his mom and said he wouldn’t have let me get away with it had he known.
“We had an argument and he is demanding I apologise to his mom for my childish behaviour and for ruining Christmas dinner for the whole family.”
Asking for advice on whether she was in the wrong, people were divided.
One person commented: “I’d rethink my marriage if my husband put his mother over me.”
But another wrote: “You should have just said no instead of stooping to her level with these mind games.”
A third added: “Great job. I cannot understand how your husband would be mad at this.”
