How do you get a girls interest back?

IF YOU WANT THIS GIRL TO REKINDLE HER INTEREST FOR YOU WHAT YOU HAVE TO DO IS VERY SIMPLE. JUST IGNORE HER AND LET HER SEE YOU BE HAPPY WITH ANOTHER GIRL AND BELIEVE ME SHE WILL REGAIN THAT INTEREST... ESPECIALLY IF SHE SEES THAT YOU ARE HAVING A GREAT TIME WITH THIS OTHER GIRL. AFTER ALL... WOMEN ALWAYS WANT WHAT THEY DONT HAVE!
