There was a Blues festival near where I live, and I went to it with my brother, and then met my friend a while later, to see different bands. It turned out he was going, and just my luck as I was getting off the bus guess who was the very first person my eyes landed on -.-
He was with the girl, and she was waving his arms at him, and shouting at him, but i couldnt quite make out what she was saying, and everytime he tried to walk away she would block him and start again. i ignored it, not wanting to meet the girl yet, and me and my brother went off to get food. We were sitting at the table when the girl and her friends walk in, and she literally stood infront of my table glaring at me over my brothers shoulder. Then she got food at sat at the very next table, made sure she was facin me and glared some more. She knows rightly who I am, but as the night went on she seemed to get more friendly to me, until she was actually in a conversation with me and some random guy that we both knew. That confused me.

Then I ended up standing with him, and some people he knew ran over and started asking him was it true that him and the girl were broke up, and he was like yea, but she wont go away and leave me alone. I then went off and met my friend off her bus, and me and her didnt meet back up with him because I decided to stay away for a while.
Then at the end of the night me and my brothers taxi claimed we had cancelled, and never appeared, and my brother shouted at me and walked away, so i decided to stay where i was until he came back so he wouldnt lose me.
I was sitting on the kerb waiting and the guy came over and took me to his friends with him because he didnt like that i was alone.

it was raining and there was no where to take shelter, and i was absoultly freezing so he gave me his jacket saying he didnt need it. he then hugged me infront of his friends and when they werent looking he whispered that he missed me. about 15 minutes later we were all standin normally and talking and the girl walks over and starts screaming and yelling at him again, about how he didnt want to break up with her, and that he should rethink everything, and that she wasnt going to let him do this (probably referring to break up with her)
she then tried to kiss him, and he pushed her away saying no, and she tried again, and he ducked saying to stop it, and she started crying, and i felt so sorry for her :/ it must have been horrible.. he settled for letting her kiss him on the cheek and then told her best friend to take her away and calm her down somewhere because she was acting crazy.

so yea im pretty sure that he has broke up with her, but she doesnt seem to be accepting it.. Im going to wait a while like you said, I want to wait and see what is clearly going on, and not jump into anything..
