MadamoiselleDuPont, I accept that you are angry and defensive, but I would urge you do think a little on these things....
"Emotional incest was more likely to develop in single parent families, where one or both parents has a developmental, psychiatric or emotional ?disorder?, or is displaced or controlled by another family member or used substitute babysitters such as the TV."
"The emotional cost of father-daughter emotional incest includes stress and anxiety disorders, mental and physical illness, identity disorders and underdeveloped and confused sense of identity and depression.
"As adults the daughters are emotionally immature, erratic, unable to sustain functional relationships or end up drawn to those which are unrewarding so keep them involved with their fathers instead.
I think, if nothing else, you need to accept that your DH has substituted your DD for you. Its going to continue to be devastating for your mental health, and its going to destroy your DD too.
You need to step back up and be the partner.
He needs also to look into therapy for himself, because he obviously has emotional needs that you are unable to meet - he needs that unconditional "big love" that spans not just his family but his past lives as well. He needs adoration and cannot build a proper adult relationship with you...having the occasional bunk up does not a relationship make! What kind of man prefers the company of preteen girls to that of his wife? What kind of man needs to send the evening lying in bed with a child, rather than socialising with his partner.
