I can tell you that 2 1/2 years out, I rarely shed a tear over this man. I'm mostly just angry now. I know it's part of healing, so I'm okay with it.
He texted me on Friday to remind me it was our anniversary. Instead of responding, like I used to, I wrote about it here on medium and ignored him. That feels like a win!

You've got this! Your mind is playing tricks on you about "how great he was". When those thoughts come up, try to replace them with thoughts about the times you were so angry you wanted to strangle him! I think that's what helped me most - reframing the fantasy into the nightmare it actually was.
