I have been the partner of a survivor and I found the 'Layman's Guide to Loving a Survivor of CSA' to be very helpful. I also read a book called Allies in Healing: When the Person You Love Was Sexually Abused as a Child.

What reading these did for me was make me aware that I too had issues, and not just my partner. I also learned that unless I dealt with my own issues, these would be triggered by my partner's issues and vice-versa. I would strongly recommend them as reading for partners of Survivors.

Also, The Karma Police podcast episode 8 (http://karmapolice.earth/) may be of interest.
