This is the main reason why most abuse stories never sees the light of the day, as most are met with disbelief, hysteria and worse still condemnation and rejection. I am glad you have been through this and survived. Hope things are better now at your end.
Most victims feel that they would be never believed, or it will be all thrown back at them. So they go into a shells as that is only way they know how to keep their secret abuse story, a secret. They get buried along.
I was also hurt at my families' silence for years but then I realized that when I couldn't understand it having lived with it for all my years, it was too hard of me to expect them to understand me or offer any form assistance, they were as stunned as I was for many, many years by it. And that probably explained their silence, as for the sexual issues I doubt whether they would have had any positive to offer than confusion themselves.
It is hard lesson being family to a survivor and trying to be supportive and loving while your whole world is collapsing at the same time. God bless them all those souls, who have, having a survivor as a spouse, a part of their life script. Brave souls, those who find enough soul stamina in themselves, to honour their soul contract to live with a survivor.
All the best to you,
