IMO, I would go back to DB'ing in a serious way. Wait for her to initiate the next contact and start over in a sense. You have been doing a beautiful job and being her friend and doing all of the things you have done have definately made her think about her actions. Just see this as a minor glitch and start again.
Nothing sucks more than knowing the one you love is out with their OP, trust me I feel your pain, but unless you have told her that you are unable to participate in any R/M as long as OM is in the picture, then she is operating on what you said and you said you would be supportive. If you can keep doing that, then definately keep doing what you have been, it seems to be working.
I had to tell my H that I would no longer be a part of R/M because his OW started texting me the other night and thats just not ok with me.
Keep up the good work and start back at the beginning, she was probably just scared and she is confused and guilty and all the stuff that goes with the A and any added pressure from you will drive her away.
Good luck!
