deal with mean girls


My current boyfriend broke up with his ex for me (i didnt try to get him to in any way) and she has had a problem with me since they started dating. Now that they broke up and she knows we have something going on she nonstops talks shit about me to people (including a lot of my friends) and she has already turned a lot of people against me. She had a horrible personality and is very materialistic and just an overall negative person and it seems that her life literally revolves around me bc she is ALWAYS talking about me. I don’t know what to do and i was just wondering if you guys have experienced somebody talking about you all the time and feeling like you have nobody.
