I already have a thread on here about dp and the trust issue I have.
Well I was left alone using his computer so I looked at the history and it says he has been visiting a site called f-buddy.
I did post in chat yesterday asking about this but I thought it was a game app he had on his phone.
How wrong I was it seems
I have signed up and it appears to be a site where you can meet other people in your area. I can't find a profile for him (good sign) but I believe you are able to look at other peoples as his history was a list practically of womens profiles 
How do I confront him about this? I am past caring about him knowing I looked at his history but I am upstairs not knowing what to do.
