Apologies for thread jacking, but just to add to the perspective of what's 'normal' these days, the OW in my H's life sent him really graphic pics of herself (or at least pasts of herself) via text and email during their A.
The interesting thing is that she's a registered psychologist who advertises herself as a specialist marriage counsellor and as someone who can help children throughout the experience of divorce (she has no children herself).
She was an ex-student of mine in her university years and invited both of us to her wedding. I thought we were friends.
She subsequently forwarded me all the email evidence of her relationship with my H in a most cold-hearted and triumphant way.
I would like to have her de-registered on moral/ethical grounds, but don't know if my perspective would be shared by the national registration board. To think that someone like her is giving advice to women in marital distress. It makes me shudder.
