Hope, I tend to agree with Blu. His behaviour is more likely to be a combination of any other reason such as: - he’s relieved you’re being nice to him - he likes you as a friend/mother - he feels safe and secure because you’re familiar and available - he can’t stand the thought that you might think he’s not a nice guy - he’s keeping you on the hook
Just focus on his actions, not words or feelings. Right now, he’s DOING two things: - progressing the divorce - seeing another woman
I think, sadly, that says it all. It doesn’t mean that things can’t change down the track, of course. None of us would be here if that wasn’t true. But it doesn’t sound like he’s been made to face losing you yet. You’re still available to flirt with, feed his ego, laugh at his jokes and references etc. Start treating him as you would your next door neighbour or coworker. He deserves to feel the sting of losing you, because you are a prize!
