I have been dating this guy for 4 months. We just had sex for the first time. I asked if we could take this to the next level and call us "boyfriend/girlfriend" and he told me that we won't work out in the long run no matter how attracted we are to each other right now. So I told him that I don't want to talk to him and I felt so used. He has tried to call me/text me at least once a day since this happened. What should I do? Do I talk to him or just keep ignoring him?
