I have no idea what to do anymore with my ex,,[more info if u open]?

Obviously this kid is obsessed with you. Since he isn't getting you back, he's spreading lies. All you can do is ignore it. And don't believe that bull crap ''baby i love you'', he just wants to get into your pants. Stay strong, and remind yourself that you aren't doing any of that crap he's saying about you. Rumors are just rumors, don't worry about it. Those rumors will come back to him, trust me.
