I did read a lot of the messages before I felt too overwhelmed to go on, and most of them were 'innocent'. He would tell her how much he loved me, I have pointed out to him that she probably pissed herself laughing at that one.
Everytime he didn't message her for a day or so she would message him telling him that she was in a lot of pain and felt really low. She instigated the message thread and the photos, she sent 3 to him and then asked to see some of him as they would cheer her up. (FFS, who would be cheered up by a picture of a dick? I find them incredibly ugly things to look at whilst 'inanimate'!)
I am not excusing the fact that he did it as he could have told her to jog on when she sent the first picture, but it does make it slightly easier to bear that he didn't start it. And when she asked if he was coming up North (where both he and I are from) he said no, even though we were, so there was no suggestion that he wanted to make it physical.
I actually have accepted that it meant nothing to him from the way he has behaved since. It's hard to explain everything on here, but believe me, he is truly, honestly sorry and is disgusted with himself.
I need a way to just get past the sadness, and I would love to get past the feeling that she has got away scott free from all this, I can see from her BF's Facebook page that they have been having lovely days out together with their DC.
