Initially, my extended family were very supportive. However, you have to be prepared for the fall out which may not come until months later. Divorce heavily affects everyone in a family. It’s very much like the stages of grief. Something has died. I write about the affects on my extended family in F.I.F.I.
Three years out, I can see signs that the shock and awe of my divorce are in fact diminishing for them.
