Review the LRT in DB. This is your best approach after the exchange you had with your H. Communicate ONLY about the kids. If he tries to drag you into a convo, ignore it. Be factual and try to only use e-mail. (You can hide your emotions)If he calls let it go to voice mail.
You planted a seed with OW and I can not see how she wouldn't be thinking about the things you said. Let it fester in her mind. It will get to her and then her trust in your H will be lost.
Come here when you need support, call a friend. DO NOT talk to H for 1 week! See what happens.
