Most Helpful Guy
I'm 80% sure he cheated on you, just by his reaction to you asking him.
Send him this:
"I don't want to hear from you until you calm down".

To be honest he sounds guilty. It sounds like something happened when you were gone. People who lie usually get angry when you ask certain things. I defiently would be Leary with anything he says especially if he gets angry or overly offensive when asked.
