<human>: Yesterday we were hanging out in his room as usual when I noticed the chatroulette tabs in his browsing history. I didn't say anything at the time and just brushed it off because he gets really defensive sometimes when I question him. I basically didn't want to cause a fight so I tried to ignore it. I didn't get the chance to click on the tabs or look at the times since he was in the same room. 

The next day I couldn't get it off my mind. In the past we have had incidents of him using tinder on his phone after breaking up for one day. After getting back together and getting caught, he went ahead and disabled notifications showing on his lock screen and keeps his phone on silent quite often. Throughout our relationship there have also been many rumors and accusations pointed his way regarding his fidelity. I never had any solid proof of him cheating and he just flat out denied everything which is why I am still with him despite these doubts in my head. These doubts of him cheating are the cause of my trust issues and a lot of arguments. I confronted him over the phone today about chatroulette and he said that it probably was just a pop-up from some of the porn sites he visits (he named a few: redtube, youporn, youjizz, etc.). I know that pop-up ads are common among these sites and they would show up in your browsing history even if you didn't click on it. Have any of you noticed pop-ups for Chatroulette? Opinions?

Can you provide a brief overview of the text?
<bot>: Saw bf's browsing history with chatroulette. Bf claims it was due to porn site pop-ups. Don't know if I should believe him due to previous incidents and trust issues.
