My boyfriend deleted some of his TikTok watch history (help)

My boyfriend has been using porn since he was 14. For almost our entire relationship, he has used TikTok to, well, do things to. I found all the girls through his watch history. We’ve had four D-days, and he has always promised to stop.

In November, he broke up with me for 1.5 months, and during that time, his addiction started again—he was looking at girls almost every day. He said it was the only thing that helped him take his mind off everything. Now, apparently, he has stopped since we got back together (at the end of December). He says he’s not addicted anymore and that he’s completely fine, but I don’t believe that at all. Recovering from this and going cold turkey doesn’t sound right to me.

He has lied before, and now he says he’s not lying anymore and that he really has stopped. I downloaded his TikTok data and saw that he had deleted around 70 videos from his watch history on different days. He says he has no idea what that could be.

What should I do?? Is there any way to send the watch history data from those days to someone and have someone go through everything to check if there are new girls there?? Or can I post it in some forum that goes through those days?
