Absolutely brilliant letter, and it encapsulates the PAIN that is adultery and betrayal, especially this bit:
I need to have the opportunity to tell you how your actions affected me, and still affect me. We do not exist in a vacuum and I believe that we have a moral responsibility to others. You may not be willing to look back at your actions with any self criticism, which is your prerogative, but I feel that I have something to say.
I daresay that you were told several lies and half truths about me and about my marriage. The modus operandii of the cheater is to justify the cheating to themselves and to make the ?other woman/man? complicit in this ? they need an accomplice who will reinforce the lie they have told themselves. If I may say you played that role very well.
Perhaps I deserved to experience the pain of being cheated on. Perhaps my husband owed me this wound. That?s between me, him and our respective consciences. What I know, however, is that you knew I existed, you knew I was completely in the dark and you knew I am a mother, trying to make a good life for my child. ...
Beautifully written, well done, did it help writing it down?
But don't send it. Write it again, even more venomously, with more pain, - and then burn it up the chimney.
Why must you not send it? BECAUSE SHE IS IRRELEVANT (especially a 3 week fling). She really is not the issue, she was a SYMBOL. For him. 'She' did not exist in reality for him. 'She' was not loved and appreciated for who she really was, any more than 'he' existed for her. Sure, they had lots of excitement and magic, but that is fantasy. And even if you had not found out, done nothing, THAT is why it would have fizzled out.
An affair is a triangle. It is a means that the betrayer uses to reduce the tension between him and the person he 'should' be dealing with, to sidetrack and distance, into a FANTASY.
It is a fantasy. This is why reputable and qualified counsellors will not see people who are in an affair, they refuse to give their fantasies any credence.
So, if you write to her, you give her far, far more weight than she deserves. It also means that you acknowledge the swamp in which two selfish immature unformed people wallowed.
Don't do it. She only hurt you, because the person who owes you emotional, legal and moral loyalty facilitated it. So focus on that.
