I have to add another 2 cents.
I got tested for Hep C and Aids when I left my husband.
Two weeks before I packed up and left, he was on a vacation with his mother.
I looked into his computer, sorting through all the trash for a week, and what I found made me wanna puke. Tons of porn, the truly most disgusting kind, and where he'd been paying for adult sites to meet others. He had videos of women he met online.
He swears he never did anything except online, but I wasn't willing to believe him. He certianly intended to. And, with that info, which was the straw that broke the camel's back, I left, got tested, and thankfully, I am ok.
