He will not sever the damaging relationship with the OW until he fully realizes that there are consequences. The OW will not budge as she loses nothing. She is confident that this will go underground if need be (as evidenced by him calling her after this exchange). The H has proven that this relationship will go underground by placing the call to her. Time for the "big guns"
