Jade -- I wonder if it's that, or something a little more complex. My wife (who though analytical is very perceptive) thought H might be trying to slow down the relationship between B and I by introducing complications. Could be. Or he just wants to have sex with a lot of people and sees it all ending. B could end all that because she is typically the instigator of that for H. He sees B settling down and he doesn't want to.
I'll find out more when my wife gets back. They sent me pictures from the beach. They are both so beautiful. I do need to remind myself of how fortunate I am when things are not going so well.
