o today i decided to check my computers history...in the last week my partner..to remain nameless..has been on at least twenty different hard core porn sites..involving oral sex with gagging choking hitting..and many other variety's...ok sure i suppose it healthy to explore the web..its not hurting anything, right? so then i look further down the smut list and see a facebook login ..with a different email..with the partners name in it..ok wait it gets better..then and then i loose it..i seea whole page of  craigs lists searches for couples..group sex..a whole page of different searches involving the same theme..what the hell! so i waited for him to get home..i didnt start in untell a while later when he made a smart ass comment regarding a new years plans...he denied having a secret facebook..he owned up to his porn..he denied the craigslist being his..and said  it was one of hid friends that comes over and hangs out...when have i had enough?
