I have been dating my boyfriend for about a year. It’s been great overall, but there’s always been this one thing that bugs me : his “best friend,” let’s call her Emily. They’ve known each other since high school, and they’ve always been “just friends,” according to him.

Now, I’m not the jealous type. Seriously. I’ve always tried to be the “cool girlfriend” and not make a big deal about stuff. But Emily pushes boundaries in a way that makes me feel super uncomfortable.

Like… she’ll come over, sit really close to him on the couch, constantly touch his arm when she laughs, and once she even used his hoodie from my closet because “it smelled like him.” What??

I’ve brought it up to him gently a couple times, and he always hits me with the classic, “That’s just how she is, she’s super affectionate with everyone.” But the thing is… she’s not like that with anyone else I’ve seen. Just him.

The final straw happened last weekend. We were all hanging out at my place, and I went to the kitchen to grab snacks. When I came back, I saw her resting her head on his shoulder and playing with his fingers. I literally stopped mid-step like, uhh hello? I didn’t want to cause a scene so I just waited it out, but later I told him straight up: “She’s not welcome here anymore. I’m not okay with this.”

He got mad. Said I was being dramatic, controlling, and insecure. He even said I was “trying to ruin a friendship that existed before I came along.” I told him I’m not trying to control who he’s friends with, but I am allowed to have boundaries in my own home. If someone makes me uncomfortable, I don’t think it’s unreasonable to not want them in my space.

Now he’s been super cold to me, and some of our mutual friends say I’m being a jealous girlfriend stereotype. I’m honestly starting to feel crazy.

So… AITA?
