Resources for adults supporting a partner with childhood sexual trauma This may be not the appropriate community, but I am looking for resources - books or articles - about how to improve the affective support towards an adult who suffered childhood sexual abuse.
I am starting a relationship with a person in her 30s who suffered constant sexual and physchological abuse as a child. She did not realize it until a few years ago, and she is going to therapy now. I am not trying to replace the professional help in any way, I just want to understand how to better support her when she talks about the things she had experienced, or when she feels guilty or unloved. I am doing my best to make her feel safe and loved, but sometimes I just don't know what to say.
I did some research, but found only books or articles for professional treatment, or guides on how to detect it. I understand the vastly difference between individual cases, but this is something so unrelated to my experience that any guidance will be very helpful.
Note: I am an academic researcher - on a completely different field -, so I might be able to cope with some technical terms or dense books.
Rape and sexual assault definitely does not only affect the assaulted, but also the friends and family as they can feel helpless, not knowing what is best to do to help and support the assaulted.
As I mentioned in the comments, support groups such as

RAINN (US)

provide support to survivor's partners, friends and family too.
The following books are recommended by Edinburgh Rape Crisis Centre
