Ok, 2 x 4 time? You really, really need to back up & figure out what your goals are. Do you want your W back? Then you need to quit allowing her to push your buttons.
Read the book again!! Start being a DB Master. You need to get out there, work on you and spend time w/ your D's, etc. She needs to do what she needs to do and you need to act as if you could care less. You need to act as if you are "done" w/ the drama.
I don't think acting like friends and allowing her to constantly talk about the OM is a great idea. Yes, be "friendly," however, if she keeps up talking about her R w/ OM, I would politely say "I don't want to hear about it anymore -- that hurts me."
Are you still in the service? For some reason I thought about you and wondered if you are still active and would be PCS'ing at any time soon.
