Could this be why she is telling you that she loves and wants to come back?
We all love to hear "I love you"....it warms our hearts and makes us feel NOT so alone.
Some things you first need to ask yourself before getting involved with her again.

What has SHE changed since you broke up that would make having her back worth it for you?
IF she's willing to USE this guy until she has another one (you) what's to say she won't do that to you as well?
