so my 'ex' best friend i guess blocked me and her sister on instagram twitter facebook and snapchat because we confronted her about many things. first of all, on my birthday 4 weeks ago we went to a dance club i work at and some people were just causing drama and i ended up running off and crying. and the only person who ran after me was her sister who hands down is my best friend for life. we have matching tattoos. but this girl who blocked us just stayed with her guy friends. shes always about guys.. she needs them to make her happy. she has guy best friends, and boyfriend in the arm who she only got with because he was available and he liked her. shes never single. shes always looking for a boyfriend and when she has one she always makes them her everything. she says i love you with in the first week. i honestly feel so bad or her. when i was single, she would always have guy problems and say "your so lucky your single" and i hated when she said that because its annoying how you can say that but always be a little hoe and chase every guy that gives you attention. anyways;

we told her that shes been acting fake lately, and making her "boys" her everything. ditching us and saying shit. so ive basically given up with her. i hadnt considered her a friend in the past month. and her sister doesnt blame me. does she have the right to block us when shes the one being a fake *itch?
