You each need to get rid of one or the other unless both relationships are open ones. Think about what broke you two up to begin with and who you really want to be with. But at the same time you're still young so play and have fun but don't go hurting those that you really care for. And always remember that if it's meant to be then it will be. Happiness is one of the keys to any relationship. Think about what will make everyone the happiest. Hope that this helps some.
