If he refuses to believe the marriage is over, then why not file the divorce papers? He won't be in denial then. Sorry to hear this is happening. Sometimes, people just can't live together. It happens. Get out of there and quit living those miserable days with him---get out and get yourself happy again! It's hard when kids are involved..... but they need to be out of this messy situation also I think. It's the sexual promiscuity that would push me over the edge. File those divorce papers and leave that loser! How could he do that to you and his kids? Favors with another man, in a parked car, in the daytime??!! Are you SURE that really happened??
