Sometimes, protecting your space means blocking out people who cause you problems.

So, what would you do if your partner’s mother had been trying to break you up since day one, and then, when you finally move in together, she thinks she can show up anytime?

Would you deal with it for the sake of your partner? Or would you draw a line and let the mother know she’s not welcome?

In the following story, one young man finds himself in this situation with his girlfriend’s mom.

Here’s what’s going on.

AITA for not letting my girlfriend’s mother into my apartment?

My girlfriend and I have been together for almost five years.

We started dating in high school when we were 15. We’re now 19 and live together in my apartment.

Recently, her mother decided to visit us, but I told her I didn’t want her in my apartment.

Apparently, she’s been trying to sabotage them for years.

Just so you understand, this woman has been ruining our lives and our relationship the entire time my GF and I were together. She forbade us from seeing each other, so my girlfriend had to lie and say she was going to see her friends, so we could see each other.

She hated me for no reason, saying I was crazy because I dyed my hair black and that I had mental issues because I didn’t smile in photos.

You know, this is complete nonsense. I’m not a junkie or a freak. I come from a normal family, I’m finishing college and have a well-paying job, but she doesn’t care at all.

Their first meeting didn’t go well.

The first time I saw her in person was when I was walking my girlfriend home.

She and my girlfriend’s father apparently went out to the store (her dad, by the way, is a cool and chill guy), and we had a conversation that went something like this: “You know, you shouldn’t worry about her like that. She got a bad grade at school today.”

To which I replied, “You know, I still love her, no matter what grades she gets.”

Her mom launched into a five-minute lecture about how I shouldn’t throw around such words, because girls take them literally. She was too dense to realize that we were dating and genuinely in love. We’d been together for over a year at that point.

When he was in the hospital, she wasn’t allowed to see him.

Another time, I had severe food poisoning, vomiting farther than I could see, and ended up being taken away in an ambulance with a fever of 105 degrees Fahrenheit (41 degrees Celsius) while vomiting *****.

Because I vomited so much, my mucous membranes and gastrointestinal tract were severely damaged, and Streptococcus bacteria entered my bloodstream, causing sepsis and septicemia.

My girlfriend’s mother forbade her from visiting me while I was lying there, literally *****, because she “doesn’t want her to get infected” (sepsis is not contagious).

Now, he doesn’t want the woman in his house.

I could go on and on with this list, but in short, she was always trying to sabotage our relationship and was a terrible mother in general.

And recently, when my girlfriend and I finally moved in together, she decided she could come to MY house whenever she wanted.

I told her I didn’t want her anywhere near my house and that she wasn’t welcome there. In the end, my girlfriend got offended and said I was being mean.

AITA?

Eek! Dealing with this sort of thing is always tough.

Let’s see if the fine folks over at Reddit have any advice they can offer.

For this person, both of them need to agree on visitors.

According to this comment, he still acts like a child.

As this reader points out, it’s both of their homes.

Yet another person who points out that it’s her house, too.

He’s got some thinking to do.

Namely, he needs to decide whether this is a battle worth fighting.
