Sexual emails

So, I've been free from hell for 1yr and 3months. My life has returned almost to normal. At least I no longer spend hours crying, staring listlessly into space, walking around with a feeling of hopelessness and dread. I have moments of anger but even that has subsided substantially. Up until now I've maintained no contact at least from my side, never contacting him about anything. From time to time he pops by, if not caught outside off guard, I never open my door to him. That being said after so much time wouldn't you think a person would stop contacting you? He also was the one that ended all contact to begin with. Shut his cell off, blocked his online account or changed screen name. Would ignore me if he ran into me in the street as if I weren't there. After all that and a year later I thought it was safe to unblock my name for email. Wrong! I received an email with a smiley emoticon in the subject line just a few weeks ago. Out of curiosity I opened it. It was a dog humping a tiger. After a year and three months this is what he sends? This is just more proof what a sick individual this is. My fault I know, I should never have opened it and will keep this in mind for the future. Curiosity just go the better of me. This is also more proof that once you know what they are don't ever assume after any length of time things will change. They are just sick, f*cked up individuals.
