My ex boyfriend and I were on and off for a long time but a couple weeks ago I finally got enough courage not to let him back in and lock him out of my heart for good once he walked away again. He messed around with so many girls when we were and weren’t together, he claims one was my best friend (who introduced me to him might I add) and I still sit in bed and think about him remembering everything that was good and wish I could forget it all and only remember the bad and move on. I just don’t know how to get him out of my head, I’ve blocked him on everything and deleted his number and all of our photos and returned all his stuff. Why do I still think of him when there’s nothing left to remind me of him? Why can’t my brain just suppress these memories and let me move on!??! And what do I do about my best friend? I don’t trust her anymore and that’s not healthy for a friendship but it’s been so long ago I can’t confront her now, I’m so lost I feel like everything’s a mess.
