I was hoping someone could give me some insight on my situation. My ex and I have been dating for 2 years and a month ago we broke it off due to arguments and us just being too comfortable with each other. During the month we have been on and off with each other. One day she comes over and after a passionate time together she tells me she loves me and says that she likes my friend. The next day I fond out shes with him having coffee. The day after she was with him too and she messages me saying she doesnt love me and that everything was fake and that we got together through infatuation and all this . Now shes with him and she is constantly subtweeting me and using retweets to brag about how happy she is and all this stuff. Shes purposely trying to get a reaction out of me when this whole time she keeps telling me to move on and apparently she herself has moved on too. She still keeps my instagram pictures up as well.
