I'm sorry to hear about your situation and wish you good will in the future.
To all the cd'ers out there, this is the epitome of why you must be up front with your wife/SO from the git-go. Once the trust is gone, good luck getting it back. Without trust, there can be no relationship.
Again, to the OP, my heart goes out to you. You might want to have your man checked for STD's. I'm just sayin'......
