I really wish you would look into IC and try to work on these problems you are having of letting go. I’m not saying it’s easy because it’s not but you are clearly suffering because you’re ignoring reality. It’s not because he’s sleep deprived. There is absolutely nothing you can do to change the fact that he has moved on with someone new. You can peacock until the cows come home and it will not change anything. Time and space are the only thing that turn these things around long term.
If you want to have it out with him that have it out with him. I just want to warn you that I have never seen that work in 5 plus years here.
You have to forgive yourself and understand that you were doing the best you could at the time. Life sometimes teaches us some tough lessons.
