I've studied Steven Stosney's book Love Without Hurt a bunch. It describes, to a T, the things you went through and felt because of having to walk on eggshells. It also describes the things I went through and felt because of causing those that I cared for to have to walk on eggshells. It also promotes healing for the abused, and the abuser. The book was a Godsend for me, via Bridgestone.
These bad things happened, unfortunately...doesn't mean they can't be overcome. But both people have to be willing...sometimes they are and sometimes they aren't.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
