By Dr. Gregory Popcak, Catholic Exchange - My book, How to Heal Your Marriage and Nurture Lasting Love, looks at the eight habits that healthy couples cultivate in their relationship and describes, step-by-step how couples who are struggling can develop those habits in their relationship... There’s a lot of confusion about what separates happy couples from unhappy couples. The book explores some of those myths. For instance, you might be surprised to know that happy couples argue about as often as unhappy couples and are about as good at solving problems!
