I’ve been in this kind of situation before, though a much tamer version. Our friend circles overlapped one year, and we gradually got close, close enough that I’d consider her one of my good friends. Then she suddenly started getting more touchy and playful, bumping my shoulder whenever she saw me, and our friends would “accidentally” push her toward me.
At the back of my mind, I had this thought that maybe she liked me. But my rational side kept shutting that down, telling myself she was just that friendly with everyone. Like, dont get ahead of yourself kind of thing.
I was introverted, and emotionally immature at the time and getting into a relationship wasn’t even on my radar as I was too focused on studying. We were a middle-income family, leaning toward the poorer side, so I saw romance as something costly and temporary. High school relationships don’t last forever anyway.
So I ignored her advances. Eventually, she probably sensed I wasn’t interested, and our interactions slowly faded until we completely lost contact when we went to different universities.
