Don't tell her that you expect a response. "Don't tell the boys that I'm doing bad things. I'm not." She already knows of the damage she has caused your family...she doesn't care enough, right now, for it to matter to her. Actions speak louder than words...BE the best father and the best CIPA that you can possibly be...with NO expectations regarding her. She already knows the things you are wanting to tell her. She already knows that you are hurt. Show her, BY DOING, that you will be and do the things that you are wanting to tell her. Think twice about sending something to her right now. She might not be receptive to it, right now. I know it's hard to just 'leave it alone'...but, right now, you might be better off doing it. You've taken the most awful hit recently, and I have empathy for you...and I believe you'll be better off, right now, just leaving things alone. Believe me, she KNOWS how you feel!
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
