If you've just started dating, go and kiss her like you mean it. She'll melt. And forget about him, at least as long as he's never kissed her like that.
If you've just started dating, go and kiss her like you mean it. Trust me, she'll melt. And she'll forget about him, at least as long as he's never kissed passionately like that. But it all depends... Does she WANT to get over him? If she does, go ahead and do this. Or anything like this. Talk to each other more often, whether that's just texting or Skyping or Facebooking or face to face or on the phone, it doesn't matter. What's most important is that you need to show her that you'll be a better boyfriend than her ex could have ever been. Become Mr. Right for her, although take her taste into account: Not all girls want that guy you're always reading about on Facebook likes. Take her out more, for movies or a fun night out or you could just go out to dinner at a fancy place. Avoid mentioning "ex" when you're together. Just be her best friend and her most awesome boyfriend, and she'll have forgotten him. Not a 100 % guarantee that it'll work, but hey, what've you got to lose?
