You guys are having some great communication, I don't see that you are doing anything wrong.
I do have personal experience on the 'moving' thing. My H has had 2 affairs. 7 months after the first one ended, we moved from Kansas to California. That helped me to let go more b/c I knew he couldn't possibly be seeing her anymore, even in some attempt to be 'friends', or anything. And I do think that it helps to end an affair if they completely stop seeing the other person.
With this more recent affair, he moved 3 hours away before it ended, but it ended 3 months after that. I am sure the distance played a role...
The thing is, the distance will most likely help end any CURRENT affair. But it won't fix whatever happened that LED TO the affair, so there is no reason another one couldn't start up for the same reason. We only went to 3 MC sessions after affair #1, and he was lying and still seeing her at the time. Once the Affair ended, I was naive enough to accept my h's claim that we didn't need counseling, it was over and he would NEVER do it again...he even got me a 3-diamond necklace to symbolize the past, the present, and our new bright future together.
Of course he had his second A 3 years later.
I am not trying to rain on the parade. I am just saying that it is good that you are talking, and moving could be helpful, too. But she must commit to working out the issues with you as well, for lasting commitment.
