Amber, I find it a little strange that you and your husband got together in the first place. Love and affection as you have learned can be very important. Since the traditional therapy did not work you may want to seek a specialist that deals with that type of thing. You are right it would be better for your daughter to see affection and be able to display it as well.
Since I have always been able to display affection it is difficult for me to understand why you can not. I think human contact, affection, love, etc are important and healthy. Like I said before I think your best bet is to seek help from a therapist that deals with your behavior.
Good Luck
