Do girls ever go back to a guy even when All hope seems lost?

happened to me before. she has a boyfriend. just play it cool. shes excited because she met a cool guy. if you make it to easy for a girl they HATE it. make her want to hang out with you. you do this by those time you text her just say hey how are you, but dont talk about being with her or how you miss her. conversate about stuff going on not what you want to go on.
