I think the disgust you feel is resentment. Resentment is pent up anger. I agree with others. It is healthy to express your anger. I expressed mine privately for a long time. Once I had a better handle on it I expressed it to my WW. In my sitch I saw her about 4 times a week at basketball games. Until I started leting go of that anger/resentment it was extremely difficult to be in the same room with her.
