Blame shifting?

My ex left me for another man, and lied about there being someone else. When we finally talked about it months later, she put all the blame on me saying she didn't feel I was into her and that wasn't confident enough. Even though I was affectionate and she used to compliment my confidence. I was very serious with this women and had introduced her to my family and inner circle of friends.

I'm not sure how to even process and how not to internalize this all? I keep falling into the idea that it was all my fault.
