Quoting justsotired2013:" He was molested by his aunt as a child... his mother was/is a whore and abused him... sent him to foster ... [snip!] ... it is definitely him!! I dont want to lose my husband again... ive been fighting way to hard for a year to just give up now..."
He really does need to go to counseling. Once the sex stops fulfilling the need he has... he may turn to other things (drugs for instance). Have a serious talk with him... let him know you're willing to stay there with the kids and help him through it. The sex is a coping mechanism, not a cure. What happened to him was horrific, and I'm very sorry.. but it is absolutely nothing to be ashamed of, and I hope he can realize that for you and your children's sake.
