@Amy, I have a tendency to over think almost every detail of my life, lol. So replaying the break up had been tortuous for about a week. I finally got past it by writing everything down. My theories, inferences, what possible causes, every single detail I could think of and finally just got it all out. Then I threw it in the trash. I think a lot of the replaying is just the need to vent and analyze with yourself or someone else. Ultimately it doesn’t matter why, although most people like that closure. Find a medium to get it all out.
