Start dating other men!!

If he has broken up with you or got another girl in his life then show him you don't need him & start dating other men. If he still loves you he will come begging you back. He might call you a whore & a tramp first as he will be extremely jealous but then he will declare his love for you. If he does come running back act as though you don't care much for him anymore & make him see he has to WIN you back, otherwise he will soon go back to the other girl or move onto a new one!!
