Mandy, this is a moving article and I'm so sorry you're enduring all this! At this point, I'd say don't worry about what you feel or don't feel. You need recovery time from all this trauma, and the feelings will come. They're there, just buried beneath a mountain of scar tissue.
Also, some anti depressants and other meds we take for depression and other mental/emotional health problems can cause subdued or less intense emotions.
I believe, as you mentioned, that your daughter has been brainwashed. Maybe you should try to pray that man out of her life. My sister and I joke about all the people we've prayed out of our children's lives. But on a more serious note, this too shall pass. It's a cliche, but true. You are in a rough patch of your journey, but in the blink of an eye, things could change. Hold onto that thought, and HUGS!
