He clearly has depression underlying everything. He may be enamored of the new wife for now but he is self-aware this is just a temporary state and that he will bore of her and so it makes him kind of a tragic character. It's like he views it as his last gasp of life, typical MLCer.
Of course, my intention is that we will have a better life going forward. He has to go on this journey alone but I want to show him that we can actually have a better marriage in the future than the past. That it's not the end of his life, but only a new beginning. I know there is a lot of trouble we will have to get through to get there but I am trying to plant seeds in his mind that our marriage will get better (while he is thinking his other marriage is just doomed to go downhill).
