LWB, I also think you made a wise choice in not giving H the cell phone number. But I do like your decision to call him yourself. If the shoe was on the other foot, you would want to know, right?
At least it seems that H is definitely over OW. But his interests in sending those photos were certainly misguided. On a side note, that woman is a loose canon! She's going to end up loosing her cushy lifestyle. She deserves what she gets.
