Help what do i do!!!?

okay so i went to my boyfriends house the other day. it was around 7am and he was still sleeping so i got in bed with him. his phone kept on going off so i checked it and it turns out that random people from a site called backpage have been messaging him about sexual favors. Turns out my boyfriend has an account where people meet up and pay for sexual favors. i woke him up and confronted him about it. i of course was really upset and felt like i've been cheated on. he said that he was going to do it to make alot of money so he can spoil me. He never met with anyone and he says that he was just going to rob them if anyone showed up. This is not ok at all and i dont know what to do.. ladies please help.
