I met with my OM twice post BD (I knew him prior to that). I honestly don't know how you haven't approached your OM by now, but the other people's advice is probably good so I won't offer anything contradictory. My encounters were just to set the record straight, man to man, on what type of behavior I expected and would tolerate. It certainly wouldn't have included drinks with him or to try and get to know him better. Eff that.
