Leave me alone

Why can't I shake the past? Specifically my exes. I leave the country and I'm literally in the same city as a long time ex. I mean I traveled half way around the world. I break up with my most recent love five months ago and he still emails me. You might assume I've been in contact but I haven't. I haven't said a word. And the the rebound even texted today. Seriously. I don't respond. There's nothing I'm doing, I feel, that is causing this. I mind my business. I've learned my lesson. So why, why continue to torture me? Why remind me if the decisions I made? I don't regret anything accept maybe believing the impossible in these men. Seriously. I've got new seeds to sow. Leave me alone.
