Had to NC for this as DH knows my username.
Recently DH invested in some kind of online certificate to develop his professional skills in a certain field, this cost us £950. Was fine with this as it was obviously needed.
We share the same e-mail address and a few days ago an e-mail ticked in, saying that the answers for his exam were ready. Turns out he's paid a fair amount of money to get the exam results e-mailed to him. He doesn't know that I know he's cheated as I marked the e-mail as unread and he deleted it shortly after.
He's now pretending that he passed the exam without any issues and I can't decide if I am more disappointed that he cheated or the fact that he wasn't going to tell me. Do I let him know that I know or should I just let it go?
