It does take Carolyn and David quite a while to realize where their family problem is coming from but they eventually get to the root of their issue.
As we all know therapy never fix any problem however open the door for dialogues and gives the parties involve tool to work to fix their problems which is what I think the therapy session had done for the Brice family. I personally will probably not advise them to ever leave therapy out of their marriage or family as a whole, I think they do need to check in every once in a while to see how they are doing as a family at least unill the children grow up and leave the house. This approach may be able to keep them grounded as they continue to grow then when the children are gone to college they can finally be together like they use to be before the children came into the picture. As we all can see it seem as if their relationship will continue to heal with time and a lot of open communication and patient with one
another.
