My ex boyfriend still tries to talk to me on Skype or Facebook, and I’m trying to get over him. I HAVE to reply to him (I dunno, I can never not reply to a message) and I don’t wanna be rude and tell him to go away, but he flirts with me, and insults me. I currently have a boyfriend and I can’t be focusing on my ex and not my current boyfriend. I used to have an interest in my ex boyfriend before I met my current boyfriend, and I think he thinks I still like him. How can I tell him nicely that I want to focus on my boyfriend and not him?
