I have/ had a friend who seriously I don't know what her deal is. She comes off as nice and down to earth but she does shit that is like... what? She was in a relationship with my friend for 6 years, two years in she did not want to be with him. Tried doing a ' fade away' where she was going to ghost him? it did not work and she HAD to break up with him. she was cheating on him with her brother's girlfriends brother during that time. She also slept with her cousins husband and when confronted she denied it. Then after she broke up with my friend she had a friends with benefits with my other friend. he caught feelings for her and she was very insistent that she did not have feelings for him ' she tried to.' told her she has to tell him cause he is falling for her. her response was ' does that mean I have to stop sleeping with him?' well- yeah you're hurting him. so after all that- suddenly they become a couple after she she said more then once she did not have feelings for him. ln my opinion she did not want the confrontation cause after pushing her to confront it- all of a sudden they are a couple. she lives with her ' best friend' who she loathes and refers to her as ' sloth' and thinks is ' slutty and needy.' but won't move or anything. Found out she slept with my ex husband years after the fact we divorced and for ten years she acted like nothing was the matter. i have no love loss for the man but I stopped speaking to her for the sheer fact that she just went on without much guilt or remorse and could not tell me the truth in all those years. I would have been angry but maybe forgiven her cause at least it meant she felt- something or was sorry and valued our friendship or whatever I don't know. just had me thinking cause I overlooked all this wtf about her cause she was ' nice.' what is the matter with her? I am baffled cause this is just shitty not normal behavior and what compels her to be this way?
