I feel puzzled for you. Not knowing what he did, I'd not circum to his pleas. I look at it this way if you can't mention it publicly here (for whatever reason) how could you deal with it face to face IRL? maybe cause deep inside of you, you know you really don't buy the bunk being sold. Many things, aren't isolated incidences, they are perhaps just the first time someone was caught. you and your self-worth are at stake here, don't feel bad, you didn't cause him to chose to make the mistake he did. You aren't responsible for his actions, he is. Many people that have criminal minds are great manipulators and prey on the goodness of others, IE-YOU!!!! Walk away, quickly, and for good, you deserve much better!
