I'm sorry you are having a difficult time. It's tough to wrap your head around some of these things. My ex h never waivered either. Well, he wasn't excited about moving out because he was going to have to start paying for stuff. But he never told me he loved me or tried anything once he moved out. He did get angry when I dropped him as my husband of FB but he was with his gf by then. And that felt odd.
I think this alters us in a way that we can't fully comprehend. Doesn't mean we can't live a great life, love again or move forward. Just means..... we sometimes see things differently than before. And I think that is exceptionally difficult to really wrap your head around.
Try to do what ultimately feels best for you. You can't help him and you are only going around once on this planet in this format. Try to focus on what is going to make you happiest.
Hang in there!
