There is so much more to all of this, chapters that I could write. I don't know if I have the energy.
Needless to say, I do feel the same as you, but it's not all about my feelings here. It's about a promise he made to me the night I confronted him. He said he needed the ability to have the friendship and that was how it was in the beginning. When I became worse he leaned on her and the rest is history. So his promise was that he was never going to touch her in any manor, not be completely alone with her, or text her any message that contained words of affection or sexual content of any kind. This all was my agreement for his friendship. He needed the friendship. I suppose we as outsiders just can't understand what it is about that, that is so important to have. Can we? So I compromised and so did he. However, if the friendship ends it can't be me that ends it or he will forever hold this little bit of grudge over it and I don't want it pointed at me.
