^ yeah i can understand in those circumstances. Its very sad what the person did, but ur one very lucky person that u got the apology.
I cant quite right the details of my saga here, but lets just say, even when i did confront the person in a subtle way, it never worked. I usually get a very sob story and tears, but nothing happens with that... they say sorry and the saga continues.
When it happens numerous times, just cant be bothered anymore.
If you ever decide to confront the person again, tell them nicely,** "I'm not having this discussion to topple you down or to make myself superior or to to show that I'm perfect. Because I'm neither of these things. I'm having this discussion with you because I feel that you have hurt me and because I believe that you are an intelligent person with an innate sense of goodness and an open mind. I have encountered evidence that you are continuing to wrong me behind my back. I don't understand the purpose of apologizing if one continues to make the same mistakes. You are an adult and can do whatever you wish. But I cannot pursue a friendship where there is a lack of mutual respect. What goes around comes around. All I can say is that I leave the matter to your conscience, for I don't have the time nor desire to engage in hurting others behind their backs. In spite of what you're doing, I wish you well."** And then walk away.
