Hi Shocked Wife,
You certainly deserve faithfulness from your dh. He seems to be trying to do the right thing by sharing his secret of CSA with you. Perhaps it will take some time for him to work through his feelings. I know you'll want to have healthy boundaries for yourself and your children. It seems like those would help your dh too. Healthy boundaries or the lack of them seem to have been the problem to begin with. Establishing them must surely be helpful.
Are you attending the conference this month in New York?
You seem to be doing the right things. I wish you success in this. Everyone involved would benefit if you can.
