There's hope if the two are willing to work together. Unfortunately, usually it's one sided where one has given up and the other is trying their best. If the one that is holding on is strong enough to carry the marriage through, there will be a breaking point where the other will finally give in otherwise that person will just give up too. In marriage counseling, it's best for each person to work on themselves because whatever the outcome is, at least that person who has tried their best will benefit most and will turn out okay with no regrets. They can at least react to the outcome in a healthier way, and will only become a stronger person. In a marriage if you don't start with the self, you most likely will not get anywhere.
