Pigeon, Maybe something happened w/ someone else. A sponsee of a friend of hers, etc. There are so many scenerios it may not even be about you as to why she changed venues, but I suggest you get thru that step and on w/ it. I felt soooo much relief when I did my 5th. Remember don't get resentful toward her, just be direct and ask her if you had done something. Resentments are our number one offender and rarely can we see our part because we just want to right.
Sugarbear gave great suggestions!
Blessings, Lily
