I experinced it......from my ex actually the story goes like ~ we dated for over 2 years...we were long distanced.He cheated on me. Break up over text(It was REALLY PAINFUL bc he was my first love) so i move on(now in a healthy relationship). Then creepy things happen...my ex was very possessive when we were together he wouldn't let me talk to boys and control freak. A few months after we break up he came up to me and said he want me back ofc i refuse him months passed and he contact me again one day at midnight saying my current bf will not make me happy and he is the only one i can marry and some shits i blocked him again..the stalking continue with his multiple fake acc on social media and he would send sms with new numbers like how ru i miss u shts then he threatened me saying he'll leak nudes of me(which he doesn't have) i said fine do it i'll sue u for sexual harrasment and more(ofc i took screenshots n records of his action) ..it has been about 4 months he stopped(i think) nor i care...BTW while he stalked me after we broke up he has 'current girlfriends' A FREAKING SHITHEAD but yea that's my story ╮( ̄▽ ̄)╭
I suggest your friend should send her location on the way to work or after work to someone she can trust and take action when things get worse...bring a tool to alert the stalker like pepper sprey or something, like it is in 'ok' stage if the stalker is just behind her and not physically stalking her(bumping into her or sth) and if he followed her until she reach home change the door lock or password...there are many way to avoid things like that so i hope she searched up online and take advice from others...HOPE SHE"LL BE ABLE TO OVER COME THIS!(๑•ㅂ•)و✧
Have you ever had a stalker? That shit is crazy and seems like not very unusual to happen these days (⊙…⊙ )
