I know that feeling all too well.  When my husband and I left our church to go to another UPC church, my husbands sister, who also went to the church we left, didn't hardly say a word to us in 8 months, even though she lives right next door to us.  Once she found out that we quit the new church,  all of a sudden she wants to "reconnect" with us and wants us to come back to "her" church.
NO THANKS!
