If what she says is true; and I heard the same from my W, you have to continue working on yourself. You have to get the reasons why she sees you as a "father" figure. What actions did you take prior the A? How was your behavior toward her? You will probably need her insight on how you behaved that led her to feel this way. These will be the areas in which you will need to do 180s.
If you can successfully ascertain what behaviors need to be modified and change them; then over time she will see that you are no longer that father figure.
If she's willing to reconcile; then a good MC should be able to help you guys determine how you got to this point.
In short, change those past behaviors, become strong and independent from her by GAL, and dress/smell nice. Her attraction to you might follow behind.
