Throwaway account for obvious reasons.

I had a casual boyfriend that lasted in HS about a month, if not less. He broke up with me due to him not being a great person. I moved on many years ago and have zero interest of rekindling anything. However every year he tries to befriend me and message me on FB around the time we started dating, but it never works. This year, I decided to hear him out since I figured there had to be a reason to his persistence for OVER FIVE YEARS. Because who does that!? Maybe he wanted to apologize for some terrible stuff he did when we dated. Nope, he just wanted to tell me how much he loves me and regrets leaving me. It's not an attempt at a booty call either. I just laugh to myself and admittedly feel great hearing he can't get over me since I completely forgot about him until he messaged me again this year. I've been rude/blunt with his past attempts to talk to me and blocked. It just boggles my mind that he keeps trying. I removed his block due to mutual friends, and he isn't a threat to me.

 Has anyone else ever had this experience? I mainly just wanted to see other people's experiences with clingy ex's and how they dealt with them.
