"I can't begin to explain the pain I am in right now, I miss her desperately and it kills me to know he is dating other guys because there was a time, not so long ago when we were so amazingly close."
We all have gone through that. We understand the pain of rejection, agony, the fear, etc. You can work through it.
"But I am continuing to work on myself because I know I must, for me and the boys."
Good. But be sure not to develop a martyr complex. When that happens resentment will set in on your side. It happens all the time.
"You must understand though, she really has pulled away from them also, that upsets me greatly and I am at a loss as to how to handle that."
I understand that. She's doing that because she feels like she needs to be totally "free" to discover herself. You just concentrate on the boys and you. Read the DB/DR as soon as possible. That will give you focus and show you how to write goals.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
