Ping, good luck. I am in a similar sitch and I am at the four month mark and, yes, I have done things wrong most of this 4 months. Bad thing for me is my D papers are filed and the D will be finalized in about 8 weeks or so. My wife is also seeing OM and of course that complicates things a great deal.
I am trying to DB as you are, but I have to say it's hard. Stay strong, you are making all the right moves right now.
Check out my thread "calling for support" if you have time.
