Blow off some steam

I had a great night last night went to the club with my friends danced laughed everything a great time no other way to put it. However, my sort of boyfriend wanted to ruin it for me for dancing with guys mind you he doesn't even go to my school. So after asking my male friends why he would get upset they said he had the right to even though he's not my boyfriend. I find that ridiculous because if it was the other way I would be over reacting. I don't normally care about things like this but I just really felt like getting this out today
