Friend Rant

so i have this friend, and during the end of 8th grade, she started dating this guy who was quite a bit older. after a while she became very mean, started swearing and making fun of me/letting him make fun of me. one of things he said to me was to kill my self, and she responded with lol😂be nice babe. whenever they ask me to go somewhere with them and i say no, they attack me asking all sorts of questions of why, is it bc of them etc. i will tell them again i dont want to go with them, "why didnt you say so in the first place?" we went on a mission trip and whenever we were in the van they were laying om top of each other playing with the others hair. she got pissed at me that i wouldnt let her text him, and when i do she looks through my messages. she got depressed bc their parents wouldn't let them date or talk to each other. she will call me gay, baby and short even when i tell her not to repeatingly. she always takes my stuff. i cant wait for the school year where ill just hang with my sister and her friends and wpnt have to deal with all this drama.....
