how? hes been cought red handed.
From what I see, you are taking it very hard, so without going into details, it's all in the mix of psychology and semantics. Been there, done that.
Believe me, because you are so shaken, and obviously devastated, you are a good material to believe a lot of what he might say to salvage the situation (if he so wishes).
Even though I gave you an idea for a revenge, honestly, I would follow the advice of others. Just walk away. Don't check anything further. The guy is still in his adventure phase, and you may just be one of his short stops. I'm sorry for being so blunt but that's how I see it. It will be tough for a week or a couple months. It isually is for the better though. Been there, done that too.
