Most Helpful Girl
It became clear that my boyfriend and I were a couple when we finally had a conversation or acted in ways that just couldn't be "just friends." So I visited a few times just to hang out with him and I suspected he liked me but I would still have described us as just friends. Then we spent one day together where it was clear we both didn't want it to end, I spent our time in one club dancing to the band with my body pressed up against him, he invited me to spend the night, and I did. That made it pretty obviously not just friends anymore.
