I started out supportive. Then I got real PO'd that he had allowed his CSA to dictate some major life decisions that I had thought WE made, not WE + his abuser's influence.
I stayed supportive but with a lot of missteps along the way. I got mad about a lot of things, said the wrong things a lot, etc.
I found ways around disclosing H's abuse but still telling the story which was good for feeling less isolated. I talk to people about it by using "I met this woman whose husband was abused....." or "A friend of mine was abused...."
It's annoying to me to do work arounds like that but it works overall.
