I have been with my 24 year old fiance for over 2 years, we have a 1 year old son together. In the time that we have been together he has talked to other girls (he has stopped), joined dating websites and websites specifically for cheating (he has stopped, and said he was only on them for the pictures), and for the past couple months he has been looking at pictures of underage girls or girls that look underage, because these girls are underage they are clothed but usually wearing little clothing or are in inappropriate poses. He even had a picture of a girl(13yrs old) that is friends with a girl that I used to babysit on his phone, which I assume he was masturbating to (he removed it a couple months ago because I asked). I have confronted him on the subject before and he said that he would stop looking at these websites. However I checked his web history and he has still been looking at these websites. I'm at my wits end, I have no idea how to approach the subject anymore. I would like it if he would stop looking at porn all together, but sadly I don't know if he would do this for me. Please help.
