<human>: Can you provide a brief overview of the text?

I am a 28 year old male who went out for New Years with my ex gf a 25 year old, we had dated for 3 months and have been broken up for roughly 3 months, she was in a bad relationship before us and jumped right in to seeing me, she needed to work out some issues with herself so we ended things on pretty good terms.  We spoke on the phone and agreed to meet up for dessert and to go see my friends band play, afterwards I said whatever you want to do afterwards you can stay or go ( I said this but figured since we hadn't seen each other in a month and a half she would want me to go along with her) We didn't have time for dessert but we went to my friends restaurant for drinks and had a great time there and at the concert.  Afterwards she said well I'm going to go, hurt I asked why I wasn't included, she said she had other things planned and didn't feel like bringing me along (there's no other man in the picture so I know it wasn't that) I'm hurt and walk off back home and sent her a text saying that if she couldn't understand why I was upset she could fuck off.  More texts are sent back and forth, between us and since her car was parked at my house I poured beer all over her windows.  She comes back later flips me off and drives off. I sent her a text today and she doesn't want to talk as she was pretty pissed about our texts, my voicemail, and the beer on her car.  I said "Ha ha, good times. See you in the funny papers." She hasn't deleted me from FB but I don't foresee us communicating anytime soon.  So redditors, how badly did I screw this one up?
<bot>: Hung out with the ex for NYE she wanted to go somewhere afterwards without me, huge fight, poured beer on her car, she is pissed.
