I got dumped

yesterday only got worse and worse for me. I started off with a straight hour of HORRIBLE cramps. My phone was about to die so I told my boyfriend I would text him later since I was in a lot of pain and didn't want to move and he got so pissed at me. "wow seriously? you won't even go grab your charger to talk to ME?" Like excuse me, we were snap chatting and not even saying anything. just random pictures and yes i'm feeling okay. thanks for asking. he never gave 2 shits about me so later that night I talked to him and said you either learn to treat me right or we're done. He decided it was too hard to try and gave up on me and everything we went through. we had so much planned out. now i'm going to homecoming alone and I have no junior prom. I don't really feel upset anymore. just like annoyed cause he was an asshole and I couldn't see that.
