<human>: I'm Stan 22 and my girl is Stacy 21. We have been dating for two and a half years. 

This is what happened. 
I went to go see her while I was in class. She was mad I think cause some girl called me over before I saw her and started talking to her. I sit next to her she's all rude to me. I leave. After class I come meet her. I tell her not to do that again. That she teaches manners to little kids but doesn't have them herself. She gets all mad walks all fast. Takes off the ring and the watch I got her before. Walks with them. Hands me them. I walk with her for longer. She won't talk to me. Then she just like leave me alone. I put the ring and the watch in her purse and she walks into class with them. She closes the door super fast before I can see. I'm lost at what to do. I love her I didn't think a joke or comment like that would really get to her.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Girl got mad. I told her how rude she was being. She takes off her promise ring and tries to get away from me.
