All couples have problems; it is normal. We bring our prior life into the relationship and have to meld two cultures, as it were, together. Affairs, parenting problems, addictions, unmet expectations, sexual and financial problems—all these can threaten a relationship. But often, with understanding and new skills, a couple can learn to stay connected. Learning to be emotionally and sexually intimate, to handle conflict well, to cooperatively parent and manage money, to communicate with one another effectively—these are the relationship skills long-lasting unions must include.
