she knew because word did travel fast and she is slutty...she has slept with 3 of the five band memebers whom are his friends and also many other of his friends, he doesn't really know her she was more of an aquantance like and friend of a friend of a friends sister. but why dump me to make me jealous is another question. when he dumped me she was there next day trying to get with him out of nowhere, and he told he no to stay away from him and that he wasn't sure he really wanted to be broken up from me...which clearly he didn't since we are back together, she was harassing him to the point he got fed up and called her out on being a slut and he doesn't assoicate with sluts...she hasn't texted facebooked or anything to him since but she will show up to shows for some unknown reason and everytime i see her 0-60 rage instant. she obviously knows who i am because he told her about me so why show up when you know you are not wanted and its never going to happen, am i going to have to fight you to get the point across...ignoring her on his part isn't doing anything, and i can't stand seeing or hearing about her slutty behavior because it brings up thoughts when she was trying her hardest to get with my bf. and in ways during the breakup it was almost not even a real breakup, he left me but still contact me everyday wanting to know who i was with what i was doing, still wanted to see me would still slip up and do things he would when we were together and like i said it didn't last long.
i feel bad because i really shouldn't worry about her as much as i am, it stupid and a wste of time and energy. the truth and all the proof of innocence has been given to me without question or fight, but i still cant stop the rage and the urge to want to beat her to a bloody pulp... even if it was't this specific person i get this way with any girl who steps out of line....i don't feel its healthy and i know i cant control what he does regardless of if we are togther or not. so its a problem i want to overcome

to add some info my bf is open and honest about things, like i said he gives me full open range to anything i want regarding social media his phone anything, i have free reign so i would know if something is up. he very open with his feelings, although not as affectionate as id like him to be but very much what you see is what you get. i have told him that situation and the breakup itself have been alot of stress and are a huge factor in why i feel these rage outbursts alot of the time, and that only time is going to make them go away. its only been 2 months since we have been back together we have been together alomst 6 including the breakup ( we decided to still keep our same anniversary and just continue on our relationship with the changes we both wanted to make). so i do feel it should be ok for me to feel this way, its still realitvily fresh. and breaking up is still a fear to me now. but i want my rage under control and im having trouble figuring out how to ge it that way.
