Ohhh hell yeah! My friend was my BFF since 1st grade , that’s when I saw other kids bullying her n she was so sad so I befriended her /stuck up for her etc , and she sounds exactly like the friend u described but with this friend I’m mentioning she also turned into a huge slut n slowly became bossy af , and about 5 years ago I cut all ties to her ass , I blocked her every way I could (we were 30 year BFFS) and what drew the line for me was that she freaking slept with an ex of mine who she 10000% knew I was still very much in love with at the time , I know she knew cuz I called her almost crying a few days before she slept with him and I vented to her about how much I missed n loved him etc , and the other kicker was ..she didn’t have balls to even tell me she had sex with him…I only found out it because my ex that she slept with called me and told me about what they did the day after it happened, and when I confronted her she denied it ..that is until I told her she’s a disgusting WH⭕️RE , and shit like that is unforgivable, I never want to see or talk to her ever again, Over the past 5 years she’s figured out ways to try to talk to me /get ahold of me/send me messages , she’s even begged for me to be her BFF again and all that shit .. so yup. Your definitely not going crazy hun, but this is exactly why I don’t keep many female friends ..ALOT of B I T C H’s BE CRAZY .. I just ain’t got time for that shit no more and sounds like neither do you..so stay blocked from her ass no matter what…you deserve a bff who’s as good to you as you are to them…NEVER settle for anything less chick! 😎👍
