I'm sorry you have this problem.
Have you disccussed this with him? Have you asked him to be supportive, or maybe he's confused by this? I'm not sure what answers may help.
If he is a reader, maybe "I Can't Get Over It" (a book) might help you both. I read it and its wonderful.
Some other types of people prefer denial. Such as, 'If my wife was abused as a child, should I hate her parents? should I be concerned that this means she doesn't like it when I touch her? does she trust me? maybe it didn't happen? maybe its all in her head? where do I stand?'
I know its cliche, but each of us tries to understand how things affect us (first) and then our beloved (second). It doesn't mean we don't love them, just that we are human and cannot escape this thought process.
I'd be happy to discuss this, if you think it would help.

I have been going thru the samething for 4 trs. now and at times I think he's coming around and then he throws a wrench in it,
At times it feels like he has a tight hold of my heart and at times he loosens his grip.
We had a big blowout and he is now in counciling himself and it seems to be working(so far).
As of for myself I have been seeing a therapist and seeing a psychiatrist for sometime now and started alanon in Jan.
So even though he wont support me I do have support elsewhere.I hope this sight helps,It has helped me so much and has given me so much comfort.Take Care and I'm here if you need to talk.

Yes, my fiance does not understand why I cannot just "shake it off". I took him to my therapist with me and that seems to help. See, he met me when I was strong and in control of everything so he can't understand this crying and sleeping all day. Or me not being able to leave the house. This sight has helped me just the few days I've been on and with everyone's support, perhaps I won't depend on him.
He does not understand my nightmares and night terrors, either. Of jumping at the slightest noise, he says "who else is in the house?.
