the title says it but basically it's a guy she did things with some years ago and since we are together he send her pictures of his boner or tries to talk to her at multiple times. I am a very calm guy but nobody messes with me like that. I texted him (we don't live in the same town) to stop doing that because its disgusting but he just ignores me and today he still went to see my girlfriend to flirt with her. I told her that the next time he comes to say that i wanna talk to him and have a real conversation but should i get into this shits? I mean hes an idiot and i dont wanna lose my time with these stupid teenager things and i dont wanna give him my attention but i dont trust my girlfriend to be clear enough. Also because of the background of the guy i am scared that she gets assaulted by him at a certain point. She's really pretty and she always tell him to fuckoff but its not enough anyway guys give me advices!
