I'm sorry about your setback. Make a mental note and do better next time. I know it's harder for you b/c you're not interested in DBing her right now, persay. But, try to look at controlling you're impulses as personal improvement. Remember how we were talking last night about R's in general improving due to the DB principles? Even though XW is belligerent, you still have an R w/ her and trying to DB the situation, as opposed to XW, might help.
