Hi, I was asking myself the same thing. I didn't get it. Why did you tell me like you did? Why after 1.5 years, why now? What did she bring to the party? Same questions. 
 
 
	I was reading a lot of stuff online and on this site and then I paraphrased those things plus my own feelings into this letter. I sent this letter to his "girlfriend" and something similar to him. Keep in mind I met her, she came into my house and met me as the wife of his friend. Also, she was in an "open marraige" and her husband, who left her 1 week before my husband dropped his bomb- thus that is the reason for the timing. She was free and he wanted to be free. He still won't admit he had a plan (however poorly executed) but he did have a reason. 
 
 
	I just kept asking and asking and asking the same why questions over email/text until he finally answered me. I had to ask about 10 times but I got to the truth eventually however discusting it was. 
 
 
	Here is my letter: 
 
 
	There was a man who felt bad about himself. 
 
 
	He needed an ego boost, someone to be attracted to him, to make him feel good about himself. 
 
 
	To fill a gap in his life. 
 
 
	You said you could "add" something special to his life. Enlighten him, Fulfill him in ways he needed. 
 
 
	Introduce him to a fantasy world where he gets everything he wants 
 
 
	That gap however is in his soul, the gap is how worthless he feels about himself 
 
 
	You thought you had the best of him, but really you were accepting the worst of him. 
 
 
	His lies, his deception, his neediness 
 
 
	To fill the horrible gap in yourself, you were searching for something too 
 
 
	Something your "enlightened" lifestyle doesn't and won't ever provide you 
 
 
	You fool yourself into thinking you are strong and secure; but inside you feel worthless, unlovable, weak, pathetic 
 
 
	I asked him what you "Added" to his life exactly and he couldn't answer it 
 
 
	you are weak and injured and selfish and narsisstic and stupid 
 
 
	the only one with worse self esteem than him is you 
 
 
	I could see it in your eyes when you had the sick need to come into my house to meet me 
 
 
	You came to size me up 
 
 
	But when you left, you knew and I knew the pecking order, 
 
 
	you don't compare to me, you knew I was a better woman than you would ever be 
 
 
	And maybe then was the moment you realized how pathetic and cheap and typical your affair was 
 
 
	He doesn't really love you 
 
 
	It was sex and excitement and neediness and trying to fill your mutual insecurity 
 
 
	And If you truly loved him, you wouldn't have let him risk the rest of his life 
 
 
	Now the life he knew was over 
 
 
	And the life you knew was over 
 
 
	You might think you will have a life with him because he can't repair what he did to our family 
 
 
	But he will only realize how he horribly he traded down with you 
 
 
	and resent you and hate you for all he lost 
 
 
	And then you both have nothing 
 
 
	but especially you
