I agree with the letting her free part. That is the hardest thing to do. I was wrapping my mind around it when H came home. One day she will realize how much she loves you, when she doesn't see you every day and when you are not available to always get her out of tough situations, and she has to go to other people.
I know it is hard, but as long as you are ok with it and you feel it is what is best for you that is all that matters. My last bit of advice is be careful with getting a close friend that is a female. That is how things started with my H. They were just friends helping each other because both of their marriages were not going well, and now...well you know, so just be careful and be sure it stays just friends.
