Mmm it seems that she's doesn't take a relationship seriously... its up to you if you truly believe she's the one you want to waste your time on?

1. When couples break up, there are reasons for the break up. It may not be what they identified as the reason for the break up, but there's a reason. When you try to reunite, you rediscover that reason.
2. You should never, ever tell friends or family about problems in a relationship unless and until you are convinced that the relationship is finished and you will never patch things up. When you tell family and friends, they take your side and view her as the "enemy." Then you resolve the issue and this is the problem with which you are left.
Going back to her is probably a mistake. Learn your lessons from the experience and move forward.
