Bright I wish there was something I could say. They are in lalaland for the foreseeable future with no clue about what they are doing or how it is affecting people they once cared deeply about.
It hurts, it really does. You will get there, but it is OK to feel bad. Mostly people who don't care much or are cut off from their feelings bounce back fast. They may act OK, but I suspect deep down they hurt.
If your long term partner betrays you and rejects you, how can you not to hurt? It is finding strategies to deal with that hurt and rejection that takes skill, and part of it is feeling the emotions and acknowledging them.
Be kind to yourself, you are moving through this - you don't see it but others do.
