If he were ready to let you go, he would have. He also doesn't seem ready to commit. I understand this because I felt the same way. I think you need to make it clear that you want to reconcile but you are no longer willing to work on your M until OW is 100% out of the picture. Right now, he has no reason to do this because you have allowed him to have both of you. This is not a slam against you, we all do things in certain situations we wouldn't do in others. However, if you want him to make a choice it seems you are going to have to force him to actually make the choice.
