AITAH for setting boundaries with an overly touchy friend??

I’m 19f, and I have a friend I’ve known for a few years who has always been very affectionate, but recently it started to feel uncomfortable. She hugs me a lot, touches my arm or shoulder constantly, and sometimes stands really close, even in situations where it doesn’t feel appropriate. I tried to ignore it at first, thinking I was overreacting or that I should just let it slide.

A few weeks ago, during a small gathering at a mutual friend’s house, she kept putting her hand on my back and leaning in while I was talking to other people. I felt tense the whole time and couldn’t focus on the conversations around me. That’s when I realized I needed to set a clear boundary.

I told her calmly that I needed some space and that I wasn’t comfortable with constant physical contact. I explained that it wasn’t about her personally, but about my own comfort. She seemed surprised and laughed it off, saying she didn’t mean anything by it, but I stuck to my boundary and stepped back whenever she got too close.

Since then, I’ve noticed she’s been more careful about giving me space, but it has also changed the dynamic between us. I still want to spend time together, but now I make sure I stay mindful of my own limits, even if it means politely moving away when she gets too touchy. I feel relieved that I finally voiced my needs, but I can’t help wondering if I overreacted or if I should have handled it differently.
