And now she is flirting with my guy!!! im getting really pissed. and she کہا she was hanging with آپ and riley first when i was already! >:(

and she flirts with the guy i like and takes my friends. she will hang with my دوستوں then say " i was hanging with them first! آپ caa leave now! " and i turned around to talk to one of my دوستوں and she was like " is your name austin? i didnt think so turn around " then she pushed me to make me turn around. and she asked a سوال in general and i answered and she was like " am i talking to you? " then i will try to talk to one of my دوستوں and she is like " stop getting in our conversation! " and today she was talking about me behind my back when i could hear her. and she is being really rude my friend tripped and fell and touched her leg and she is like " get off me! " she is blonde and she is dying her hair just like im about to get mine! she is a fucking copier! i need advice!
