"Be careful about over-sharing.
Don't give out intimate or private marital or step family details 
that would embarrass or shut down the heart of anyone you love.  
When you share your frustrations, 
make sure you keep the focus on your feelings and behaviors.  
Don't focus on your husband or kids and what they are doing or not doing.
Choose your friends wisely by choosing wise friends.  
Make sure you don't spend too much time with any friend 
who tries to turn you against your husband, children or stepchildren.  
Friends help preserve families, not push them apart." 
[Gary & Greg Smalley, "The Heart of Remarriage"]
