You know some people just cannot share what is wrong, they eat all their pain, afraid that the world will find out what a fraud they are, I was that way for many years, you may never know what your friends burden was, he might have been riddled with shame and guilt, please forgive him, I am sure he did not intend to cause you this pain.
I had a really bad spell a few weeks ago, the Penn State scandal, the jusge beating his daughter, one of my abusers moving back to MO turned into the perfect storm, I completely lost control.
My therapist tells me that men are coming out of the woodwork, men who have never ever spoken of their sexual abuse, they could not cope anymore, they believed like I did that people would blame them, they have no support, they are worried about being labeled, laughed at, reviled.
So please forgive him, please remember the things that made him your friend.
Best of luck to you,
Bill
