Good for you! People somehow mistakenly believe that they owe something to their parents, the parents who neglected, mistreated, abused and shunned their own children. We don't owe them anything. And telling the truth does relieve a lot of stress.
I had an ambivalent relationship with my JW mother until she died. Not as bad as many experiences I've read here, but not always good, either. It took going to a psychologist for therapy to finally realize that it was OK to feel the way I did. What else could she expect from me, considering all that had gone before?
