Think of your H as an alien - he's doing things that are very out of character. Most of us are faced with this with our WAS. They become the opposite of who they were. Try to get your mind off OW as much as possible. I know this is so very difficult to do but it's not helping you at all to keep thinking about her. They're behaving like teenagers - those feelings are not love but infatuation. Try to use the stop sign technique from DR when you find yourself thinking about them. Your H is pretty much following the MLC script in most of his actions. Remember do not believe anything he says and only 50% of what he does.
Hang in there! Focus your energy on your job interview.
