This gut wrenching guy is Still a big part of your past, and haunts you with the 'mindfuck situation' you went through with him. It has even caused you to seek help.
He took over your life even after the train wreck. You can't move on, live a normal life, and even the site of his picture causes your stomach to churn and burn.
Until you are through this bad nitemare, and have found a way to finally cut the cancer out of your life, just the mere thoughts of him will continuously make you a Nervous Nellie. You need to take control of your life, and Stop being 'attached' to what was at the very end. He's gone, it's Over, and thank God you 'don't talk.'
Being you were Strong enough to 'block him on your phone,' someday I believe you will be even stronger to block him from your mind, so you can learn who you Are once more, and find the closure that you need to close that chapter of your life forever.
