You should let it go and the only way to let it go is to forgive him from the bottom of your heart.. not a lip service "I forgive you" statement on WWW or even to him directly...

Its a statement you tell yourself and he will feel it in your face/behaviour when you interact next...

I said forgive and not forget... you can always learn from the experience and make needed changes. one of the lessons may be that he is untrustworthy and so don't trust him with anything until you have reason to consider otherwise..

PS : I have been led to believe that email comms can be treated as contract, so check it out with legals..
