forgiving and betrayal

My wife told me about 9 months ago that she had been having a lesbian affair with her best friend. This news was not completely shocking, because I had suspected it from the beginning. I had even confronted about the affair several times.

I appreciate that she finally told me and said that she wanted to make our marriage work. It has been a long 9 months. I can forgive and move past the sexual discretion. The part that I am having an extremely difficult time with is that she still insists that she can be a friend with her AP.

They workout together 6 day a week and spend at about 4-6 hours together daily. I don’t feel like they are still sexually active, but I feel like I am still being betrayed every day.

How do I continue to forgive? I have read so many opinions on what to do. Become a good listener, be patient, try and understand. How long do I endure this?

I ask myself, why? Sometimes my only answer is just don’t give up. I realize I can only change myself; I cannot change my wife. What do I do?
