I was thinking a friend of mine is a friend- the result is that she only came into my life with the will to destroy me. She followed an insidious plan and entered into partnership with a person that is "nicely said" a bastard.
I kicked him out a few months ago, now her. I know that she will regret her intention deeply, but I wish her nothing else than a burning hell on earth. Am I wrong?
You're angry, you feel betrayed, you're hurt and you want to hurt back. Those emotions are normal in the aftermath of such a betrayal. (I'm sorry you are going through such a thing.) The thing is, if you allow those emotions to control you or to fester within, you will become bitter and only end up destroying yourself.
The only healthy thing, imo, is to work towards forgiveness, no.matter how hard because it will benefit you in the end. Forgiveness means you let go of the need to exact revenge or mete out justice. It doesn't mean you can't be angry or feel hurt and it doesn't mean you need to act like this didn't happen.
I was in a situation where I was deeply betrayed by someone very dear to me. It took me years to work through that pain, but the day I could finally say "I forgive you" and mean it was the day I finally found freedom. (It was so bad I had nightmares about this person. They ended immediately.)
