My son is 18. He knew about the affair before I did. I found out, after my H left, from my son that he had overheard my H on the phone talking to OW and figured out what was going on 4 months before my H left. My son also knows the OW and has always disliked her. My son is very angry and refuses to have anything to do with my H other than polite conversation. In his mind what my H is doing is wrong and unacceptable. He has lost respect for his Dad, who before this he really looked up to. He sees his Dad as a fool.
My H is trying to buy his favor. My H does not get it at all.
