I started talking to this girl from this social circle (that I'm not entirely in but one which I know mostly everyone) about 3 weeks ago. Things have been going pretty well lately, we would go to the gym together, watch shows together where she would just sleep over at my place, and study together at school. And we finally fucked yesterday.

I could tell she likes me, but I just don't know if she's using me as comfort. I made the mistake for always calling her cute and telling her I like her, but she would never say it back to me. She would also never show affection in public, not even just holding hands even when there's not much people around. But once we're in the bedroom she would show me all sorts of affection, she would hug and kiss me from behind. I also know for sure that she would not want to let the circle know something is going on between us, which I don't mind but I just want to know what state of our relationship is in.
