Relationship advice!

So my boyfriend of going on one year fell asleep much earlier than me. I decided to go through his phone, FOR THE FIRST TIME ever. And I found something I prayed would never happen to me. He had been using a site to pay women to send him videos. He paid 3 different people. And messaged with some of them. This is the first time anything has ever happened to me like this. I could use all the help I could get!
