You never go into a marriage expecting to get divorced. You go into a marriage expecting it's going to last forever and you have a lot of ways you dream about the future. You have all these expectations and then you have to adjust those expectations and it can be a very unnerving confusing time.
In a sacred ground like marriage you find yourself out of it at certain times for reasons unknown that can be destructive. There could be a demon that kind of comes out and overtakes you.
