O/T perhaps... A Good Book - to help one see through the FOG of Emotional Abuse
Fear. Obligation. Guilt.
I thought this was such an eye-opening book:
Emotional Blackmail: When the People in Your Life Use Fear, Obligation, and Guilt to Manipulate You by Susan Forward & Donna Frazier
For learning how to deal with parents, in-laws, the husband's/wife's ex, the guilty parent, kids and even my own self-sabotaging thoughts as a second wife and stepparent.
My DH's ex-wife was and is a Pro at emotional blackmail. And, sadly, I actually found myself becoming a pro too because it seemed that's the only way I can get my husband to react to some things, so CONDITIONED he was to this kind of interaction.
