I am not entirely sure exactly what you are asking what you need to do about this situation. I'm sorry I'm not trying to be obtuse but I will say this about your question.

Honoring your father and mother does not imply that you have to have feelings for them. I believe it does not mean that you have to deny what was done to you or act as if it was nothing but it does mean that anything to do with them you just do it with the same respect you would expect from others.

I hope that makes sense.
