I never felt that at all and I couldn't have understood it until a few weeks ago, after all, when I changed my name, I was the same person as I was the day before I changed it and what is in a name?
A few weeks ago though, my ex referred to me as me - old male me- being gone forever. And well, now when I look back, I am unrecognisable from what I was. For the first time, I felt like I was truly someone completely different, looking at someone else; someone who I felt responsible for the demise of. I felt guilty, and instantly hollow. It's so odd.
I suppose I am over it now, but it makes me sad when I think about it still.
