I was on Facebook and came across a meme, I "liked" it and then realized it was posted by the business my ex girlfriend/FP started with the guy she cheated on me with. It's been over a year since we last spoke, and things ended really badly. I have so much guilt and remorse about how I acted and handled things. Even after all this time I still can't let go of it or her. Just when I think I'm doing better something as dumb as this puts me back to square one. Now my day, and probably week is ruined all because of a meme. How do I let go and forgive myself?
