have you really thought about WHY you feel like you can't let go and forgive her? what is that issue really stemming from? did it make you feel insecure that your W would approach you about this on a number of times, or make you feel like she was saying you were not enough for her? i only suggest that because i think that's how i would feel were i in that situation, and those can be difficult feelings to overcome. i agree with soleil that maybe IC for you to help get over this issue and potentially MC to continue nurturing your M. you put a lot of work into getting your M to a good place only to give up now because of something she asked about but never actually physically did.
as a woman, i know that sometimes women also bring those sort of things up because they think its something their H would really want. kudos to you for not giving in to her, though, it says a lot about your character to not jump on a chance like that. most men think it's just about as close to heaven on earth as you could ever get...but i know from experience that (especially when it's a good friend) it really only messes with the heads of everyone involved and can often end up breaking up friendships (or marriages).
stick to DB-ing. and really meditate on why you can't let go and forgive...
