you cant tell her to do or not do anything. you cannot teach them anything. you cannot persuade or get her to realize anything.
when i was going through my D, my x and i had a sit down and discussed what was going on. it was not DBing, it got ugly at times, but some parts went well.
during the conversation, as she was saying she wasnt sure what she wanted, i gently (and i made very sure as i said it without any anger or force) to just let me know what she was decides and not to spring it on me.
the very next day, i overheard her telling her mother that i was demanding that she tell me everything she was doing.
so. the point of the story is the WAS will hear things differently than you say them. and in my case, will twist things to their advantage.
