Yeah, you just gotta stay no contact no matter what. I can tell my AH is trying to get a rise out of me. He knows that I hate being accused of things I didn't do and he has nothing else to accuse me of so he invented this idea that I am having an affair. It drives me nuts because he tells everyone this, he says he had a private investigator go by my house and saw some van as evidence of my "affair", which is impossible because I don't even really have any friends that come over so I have no visitors! He has been on this topic for months, I should just let it roll off my back but to be honest, it really bugs me! I am working very hard to let it go and not let him know it drives me crazy. It is really a challenge not to engage, but it's the only way to go. There is nothing you can say to make them act normal.
