Annoyed

So my bf and I just gotten together recently and there’s this girl that’s always on him. My friends have been telling me about this, but they say that he actually “pushes” her away and I love him for that. I also heard that the girl was talking about me and how I’m just his “ex”🙄 Sometimes I do wonder why are some females like this and can’t actually leave males alone especially when they have a gf.🗿
