Grace - I skimmed back through your threads this morning (reading threads has become my norm on my morning commute) and I with each post I see the slow but steady awakening of a formidable woman who is looking forward to wherever this journey takes her. You are an inspiration.
Others here are right, he still looks to you for emotional support. If you choose to deny him that, then make sure you are doing it because not seeing him is something you need it to fully heal, not because you want to show him what he is giving up. I don’t mean nice him into coming home, or allow him to cake eat, but your H sounds messed up in more ways than one, and a little compassion (with appropriate boundaries) for someone we once (or still) love is a good value to have. But, if doing that hurts you in the process, then leave him to him he to his mess.
