Christine, with your fabulous DB attitude, you don't really need me to tell you this, but I will throw it out there anyway because it is a mistake I made not once but twice (some of us are slow on the uptake).
Don't overreact in any way. If he mentions the call or OW, listen to whatever he has to say but don't react right away. Stay cool as a cucumber. Do NOT let any emotions get to you. If he doesn't mention it, monitor his behavior but don't talk to him about it and don't let it bring your great attitude anywhere near eggshell land.
