AITA for not letting my exs mom in when she showed up unannounced?

A 45-minute drive away from her dad, this mom thought she was just dealing with the usual “crazy MIL” talk, until her ex’s mom showed up like she owned the place. It wasn’t a normal visit either, it was a window-tapping, unannounced appearance that made her feel like she had zero control over her own home.

Here’s the messy part: she has sole custody, and her ex’s family lives a nine-hour drive away. The apartments are not gated, so anyone can pull onto the property, but buildings need a key. So when the ex’s mom knocked on her bedroom window, she realized the woman shouldn’t have been able to enter at all. Still, she let her in the first time, told her to give a full week’s notice, and even watched the kids for a bit.

Then it happened again, and this time the ex was texting, the police were showing up, and everyone acted shocked that she didn’t just hand over her kids.

Original Post

This happened a couple of years ago but I was talking about crazy MIL stories with a friend and she thinks I was an AH. I have sole custody of my children.

My ex and his family live about a 9 hour drive from me. One day at around 9am there was knocking on my bedroom window.

I peeked through the bottom of the blinds and just see woman’s sneakers. So I peek higher and make eye contact with my ex’s mom.

All I can think is WTF? The apartments where I live are not gated so anybody can drive onto the property, just not go in buildings without a key.

Which means, ex’s mom couldn’t knock on my door because she couldn’t enter my building. Anyway, now that she’s seen me I change and go see why she’s there.

Only reason why she has my address is because a few months back she asked to mail some stuff for the kids & I dumbly gave her my address. She tells me she was in the neighborhood.

I asked her why she didn’t call me before arriving and she said it was a “last minute decision”. I let her in and she sees the kids for a bit.

When she leaves I tell her next time she needs to give me a heads up before arriving, and I’m not talking 10 minutes before, I need at least a 1 week notice. So, this is where I might be the AH.

About 4 months later she pulls this stunt AGAIN. When I hear the tapping on my window.

I know exactly who it is. I don’t bother looking out the window.

She starts calling me. After the 5^(th) call, I answer.

She tells me to open up because she wants to see the kids. I’m like what?

I’m not even home- why she didn’t tell me she was coming? I’m 45 minutes away visiting my dad with the kids.

She demands dad’s address - I refuse to give it to her. I tell her I have no idea when I will be home.

Yes, complete lie. Anyway, she doesn’t believe me, she thinks I’m home, again says it was a last minute decision.

I h**g up on her, I’m getting texts from ex demanding I let his mom see the kids. I tell him what I told her -I’m not home.

Imagine my surprise when I hear the police banging on my door a few minutes later! I don’t answer.

I get a call from a random number - the police officer. He is there to perform a wellness check because ex’s mom hasn’t heard from me in 3 days and she’s extremely worried. I tell him she is lying- I just spoke to her on the phone, she showed up unannounced. After that phone call I get a text from ex calling me an AH and how hard would it have been to let his mom see the kids when she drove all the way there just to see them. It was like she was on a weird power trip.

Boundary Setting Insights

Boundary setting is a crucial aspect of maintaining healthy relationships.

Familial relationships often carry complex emotional dynamics.

The first “last minute decision” visit starts with sneakers at the bedroom window, and OP is immediately like, “How are you here if you can’t get into the building?”

Emotional responses to boundary violations are often rooted in previous experiences of trust and safety. Research published in the journal Emotion shows that individuals with histories of trauma may react more intensely to perceived intrusions. This heightened emotional response can be a protective mechanism, signaling the need for safety.

Understanding this emotional context can help in managing reactions during stressful encounters. Recognizing that these feelings may stem from past experiences can lead to greater self-compassion and a more measured response in similar future situations.

To effectively manage the stress arising from unplanned visits, mindfulness practices can be beneficial.

After OP lets the ex’s mom in and sets a strict one-week notice rule, you can practically feel the tension rising for the next stunt.

This reminds of the late-night call that turned into a full-time chauffeur job, after a $600 “gift”

went sideways.

Effective communication is crucial in navigating familial relationships.

Unannounced visits can trigger feelings of anxiety and vulnerability, which are common in individuals with attachment issues. Research from the University of Michigan illustrates how attachment styles influence reactions to perceived intrusions. Those with insecure attachment styles may experience heightened anxiety during such encounters, viewing them as threats.

Understanding one's attachment style can provide insights into emotional reactions and guide strategies for coping. Developing secure attachment behaviors, such as establishing trust and consistency, can improve how individuals handle unexpected situations.
