Confusing or Jealous??Who know?

Everytime i open my facebook, i also will take notice of her profile, attentive to her new updated..I know i'm not excellent as her but sometimes i still will compare with her...Even though they end up their relationship long time ago, but i still care about it. Maybe i have listen something from others before. They had denied but who can estimate their future? However, that was none of my business anymore.. If they really get together, i will wish them..the most important is that last time they broke up is because of some small matter. I don't hope that they have any misunderstand and cant be a friend! So, i hope they can disengage themselves from the misunderstand..
