I just picked up on your full sitch. Very similar to mine - have a WAW (except that we are separated - I have an apartment not far from the family home). There is an OM that I flushed out at a counseling session back in Dec. W wants to stay friends - admits that I am her best friend but that we became roomates. She apologised the other day for "giving up" - perhaps a baby step but there is a lot of confusion on her part.
So I have been detaching as best I can. Being really friendly, etc. Acting as if. Going to pull some doosey 180's in the next month or so. I'm inspired by Hardheads posts that I know you had read and will start employing those strategies. In the end, my W I see wanted someone more in control of themselves. I wasn't that person. This OM might be (he's a cop if I understand right so probably all rough and tumble, blah, blah). I don't know for certain if it is just an EA or a PA at this point - working on NOT CARING. DB's for myself. One month in and I can already feel the difference in ME. WAW is seeing it to but fighting it a little. It is about patience.
I'll keep you posted on my sitch and certainly be watching yours. Hang in there.
