P.S., the silent treatment game doesn't work with me; I lose respect for people that play games. When it's serious business, the direct approach is the preferred approach. Leave out the emotional fillers. If he respects you, he should gladly work through issues until everyone's happy. If he continues to disrespect you, I honestly think he needs a strong father figure to lay down the law and get the respect back.
Hopefully an ENTP guy here can shed some light on alternate solutions.
