I just saw your post about starting a new IC and just wanted to offer some thoughts.. for whatever it is worth.... :-p
You know I had gone to IC for quite sometime (my IC was also our MC for the 3 months before she moved out).
One of the lessons I had learned during my IC sessions (which lasted for about 10 months - once a week) was that I spent a lot of time trying to figure out how to "fix" my WAW.... it wasn't till I got more focused on myself did I start "feeling better"
Perhaps I would have felt differently if my WAW wanted to try to fix herself, or wanted my help.... but it goes back to what an old mentor told me
Success is typically predicated on two factors.... knowledge and desire.... you can offer all the knowledge/insight to her to help her but if she doesn't have the desire, it will never be successful
I think you've done everything to offer the logical reasons to make her want to fix herself... but it sounds like she still doesn't.... God may be the only person who knows what the answer is to what it will take to make her want to try.....
So for now, while she's not showing that she wants to work on herself.... I would focus the IC on yourself and how you can help your girls.... At that point, I found my IC to actually be more "satisfying"
Hang in there bro!
