I was just reading through some of your posts from the last few days. I would be careful with the whole 5LL thing. It is nice to read up and educate yourself on these things to use possibly when your two are back together but I would shy from using it now aside from regonizing what is a good way in which to communicate with your W (kind of like Michele says in her book, picking the right medium to get the message across). I think if you really try to apply it now then your W will notice but it won't be all good. She will like what you are saying, etc, but it will seem foriegn and wierd to her. Since she has trust issues she might also question in her mind....who is the real Neil, and she might question whether she ever really knew you.
I think I would stick with the DB principals and make it about you. Another book you might consider is Dr. Phil's Relationship Rescue.....it is very similar to DB in a lot of ways (basically, he says "you own your R" and you can make a difference. This book is good because it is actually in a work-book format.
Just some thoughts, hang in there and be yourself, your not the bad person you guilt yourself into believing you are.
