On Saturday I saw this girl who is a close friend of mine who on the Friday of the previous weekend I saw talking to her bf and then after they talked I saw him walking away from her with an upset look on his face and when her and I hugged she asked me how I was going but in this way. "How's my boy doing?". Back to what happened on Saturday her and I hugged when we saw each other but I noticed something was up after she looked at her mobile phone because she started crying also her bf who is normally there with her wasn't and at that time a friend of hers comforted her and for most of the night she was still looking upset when I saw her. Later on during the night her and I were dancing and there was alot of very close body contact going on and she was practically all over me while dancing with me, she then once again called me "her boy" and after the dance her and I hugged each other tightly. Then she mouthed something to me which I'm not sure with what she said because I'm not good at reading lips but after that I noticed that she was happy instead of being upset so I think I may of done something but I'm not sure. Please help because now I'm not sure what's going on.
