I would have to agree that you and your wife should make it VERY clear together that he's crossed the line. I know my husband would want to take the guy down in a major beating as well, but that will only land you in jail. You and your wife need to put your feet down together and make it clear he's crossed the line. As a wife I would feel uncomfortable if one of our friends was making advances like this. I would be trying to advoid them at all cost. And I think it comes down to do you value your marriage more then the friendship? You've told your friend, hey you crossed the line, but he's let things chill out and started this crap again. No, he's blown his chance. It's time to cut ties.

OK, I had a red flag go up when you said somethng about his kids. You said the kids had an "Incestrial episode"? DING DING DING, bells, red flags. Something is not right in that house. Did he tell you that his kids did this?? This is something that needs to be reported to child protective services. If you know about this then your obligated by law to report any spected child abuse. I know your thinking WTF, but there is something going in the house that isn't right. Maybe that's the reason the daughter is wanting you to pick her up from school. She trying to advoid being around her family??? Just a thought from an abuse survivor, something isn't right there.
