Completely agree with this. I think he's probably been doing this since LONG before, he just told you about it now because he could blame you for it. Regardless, his statement "there will be consequences" is messed up. You don't forgive someone and then punish them. You made a mistake because of a series of really unfortunate events that all came together. He actively went out and was on craigslist and paying for sex!!! Totally on purpose, no accident or mistake there. If you don't believe him, trust your gut. It sounds like he might be a sex addict but even so, he's opened himself up to all kinds of drama and disease, and you are vulnerable by extension. It sounds like this is pretty elaborate and I doubt he will stop, I'd run far far far away.
