<human>: Condense the text into a few key points

So two days ago I was at a rave and had been partying for about 6 hours at this point dancing and shit like that. I was exhausted and really needed to sit down. My girlfriend wanted to go back and dance more but a few of the people wanted to wait until this girl got back and then we go back to the show. This girl happened to be my ex. But I dated her in grade 5 and I am now in grade 12. So 7 years has past and I didn't even really remember at the time that I had dated her because I didn't date her for long. My girlfriend got really pissed that I was waiting for my ex and ended up being mad for the rest of the rave and the rest of the night at the hotel. She is still mad that I did wait for her and thinks I love her and want to be with her when I said "I'm exhausted I'm just going to wait till this girl gets back cus I'm to tired"
<bot>: tired at a rave. Girlfriend got very mad because I waited for my ex because I was tired. She is still mad.
