OK, fair enough, but if you are pretty certain that she is lying to you about what she is doing now, do you really think that you will feel any more trust if the two of you agree that she and he should just be friends? How will you feel secure that she's not still seeing him and that they are lovers?
This is what I have been trying to say about building the trust. If you can't get that then no matter what you agree, it's going to be very hard to have a functional relationship, in my opinion.
