Hello Patricia and thank you for your advice.
You know what you said is exactly what her sister told me (with which I still keep in touch, since her and her husband were our closest friends during our relationship). She said that it had nothing to do with the way I looked and that she felt the need to live some things.
As for what I said about wanting to show to her what she lost, I did not mean that. As I said I do not blame her for our breakup and have not any bad feelings towards her. Maybe it’s something I said to myself in order to lessen the pain. But you are right it is a wrong attitude. It’s just that it just sucks you know. And it hurts so much.
I have promised to myself that I will move on and live my life.
