My soon to be ex was ocd and addictive to the extreme. He was totally addicted to porn, he would do his thing in front of his computer at least three times a day if not more, even when i was home. he showed no shame whatsoever, and, he treated me like one of the porno chicks.
it got worse and worse as his bi polar moods got more volitile. I feel badly for anyone who goes thru this knowing there may be something wrong, confused and wanting to correct the behavior. The ex did not try to right the wrong, instead he isisted it was normal. He even went to the extreme of buying a pump and having bruised skin, thinking nothing of it.
I would hope there is some sort of support group where you live that could guide you and help you throught this?
