I think that forgiveness it’s only for psychological calm.
you forgive or not,this doesn’t have to do with other’s life or happiness.
some people can forget,or ignore some facts and go on with their lives.
i don’t agree with this because i think that we must better be clear with any person and don’t have problems,repressed feelings etc.
unfortunately i have repressed feelings with some people,but I’ve tried to successfully ignore them,not because i have the chance to fix them,but because i hadn’t unfortunately.
so,whatever you said is a fact,you wanted to tell it,so don’t take it back.
whatever you told was your feelings that trying to defece your self. it’s not your fault at the first time,she was the explosive,you were the eruption.
try to just ignore the past facts and feelings,do more good to yourself,and someday you’ll love you.
that day you will understand that your actions were expected.
and focus to yurself.everyone does that,ex doesnt matter,she’s a piece of shit in your life.if you’re feeling good with yourself,you’re succeed in the whole journey of life.
good luck.
