why is he coming back?

[MrBond]

Just because you see a psychologist doesn't mean you're "damaged". It means you're trying to make sense of things. The problem is that you can't make sense of it because it is not in your control. HE has the control and it's the unknown that's driving you crazy. You're wondering what could YOU have done to save things, etc.

Well when it comes right down to it, YOU can't do anything. He was the one that changed things. So you feel abandoned, hurt and alone. Trust me. We've all been there. Take things one day at a time. But most importantly, live for YOU and not for HIM.
