Feeling Betrayed

So as most all of you know I have a very tumultuous relationship with a family member.  Last week the final straw broke the camel's back and we are no longer speaking or communicating in any form.  During our last conversations both she and her husband revealed that they had heard negative comments about them circulating locally and that I had better watch my mouth.  This is THEIR town and basically we need to watch our backs.  Also, she wants no more communication with us and their family.  I had confided in someone at church about the conflicts so to get some spiritual advice.  This person betrayed me and added fuel to the fire.  I don't know who to trust anymore.  I feel sick.
