I would just add that I would hope that SS would be fine with you saying, much as you have done here, 'Oh, and another thing, seems silly somehow but thought I'd mention it...H once...H always said...H never...'
I don't think you need to feel like you have to have an 'outsider's' perspective yet. You are recovering. SS will (surely? can others confirm?) be able to deal appropriately with unsureness and mentioning things that could be totally normal or could be an awful sign of abuse in the bigger picture.
And hopefully (again, someone else confirm, please!) they will also be able to deal with it appropriately if you tell them about something and say something like, 'I know it seems crazy but I didn't do anything at the time because it seemed so little/reasonable when H explained it/too difficult because I'd just had a baby. I'm slowly realising that it probably wasn't okay but I'm having a hard time coming to terms with it.'
And by 'deal with it appropriately', I mean, they will focus on the picture you are giving them of a controlling abuser and the effect he had on ALL of you, and what action is necessary to protect you ALL going forward. Not focusing on blaming you in any way.
Sorry if I am going on a bit, but it seems really important that you are just as honest with SS as you have been with us, in fact, even more so.
They aren't in the same category as other people, the neighbours, your mate from toddler group, whatever, where you probably do need to protect yourself and be circumspect. Not with SS.
