You are getting a lot of "script", Alan. Generally, we see one of two things. Either every problem in their life and the M is the LBS fault, or the other is that it is THEM, not the LBS.

The reality is, if there was nothing wrong with the M, then why would she seek someone else?

She's giving you reasons / justifications / rationalizations for what she is doing.

I think the biggest thing for you to understand is, there is something very wrong with this guy. Your W is a married woman, yet he is "involved" with her. That said, most As end, eventually.

DB was the first book and it is very good. The second one is more like a "workbook" if you will. So for reading, I would say read DB. Use the chapters in DR to work through creating your plan.

Also, remember that you really want to take this time for your own growth. While your W won't tell you there was anything "wrong" with the M, there are certainly things that you could work on. What might those things be?

You want to become a man that only a fool would leave and this growth of yours will be positive in your life and any future R, whether your M is saved, or not.
