<human>: I need to know if I did the right thing or not in cutting this girl out of my life. She is super smart and beautiful, I really do like her. We were never official, we only went on three official dates. I saw her at a party a little while ago. It was nice, then we went to a bar where she made plans to go to a Ren fair with two other guys (who we talked to at the party). This all happened in front of me. We exchanged numbers and she said I didn't have to come if I was busy. Which admittedly I was. We all split up and I walk her to her car, she bought me street tacos. She ask me how old I thought the other two guys were.

I ask her, "What's going on between us?" She said she likes hanging out with me but doesn't want to be in a relationship. I told her I like hanging out with her too. I told her I can't help but feel jealous if she dates anyone in front of me. This just happened. In a calm voice, I told her she can do what ever she wants. I told her I'll see you around, I kissed her gently and went home. It hit me a few hours later when the tears came.

We weren't officially dating, do I have a right to be upset? Am I just a back up guy? Was it a test? Did she just want attention? Was she trying to make me jealous? Could I have handled it differently? What was I suppose to do?

Can you give me the gist of the text in a nutshell?
<bot>: Girl I just started seeing made plans to see two other guy in front of me. Broke up. Did I over react?
