Tyler and his fiancée Kristen have known each other for seven years, but only recently have they started to learn that each has not been totally honest with the other. Kristen, 24, reveals that Tyler thinks she separates whites from colors when doing their laundry, but she really throws all the clothes together in the same wash. "I haven't turned anything pink or orange yet," she laughs, "so what's the big deal?" Tyler comes clean that occasionally he's told Kristen that he enjoys her cooking when he hasn't, explaining, "I didn't want to discourage her."

These may seem like little white lies, but could they turn into something bigger? "Lies of omission is what we call them," says psychologist Dr. Judith Sills, who states that in cases where the truth could be hurtful and not constructive, it may be wise to keep it to yourself. "You don’t really want to say, 'Your cooking is the worst,' but you might want to say, 'I really appreciate how much you’re cooking for me and I cut out these recipes that you might want to try.'"

Dr. Sills commends the couple for confronting honesty in their relationship. "What a great moment to be talking about it, because you know you can change your relationship, because it’s like a cake," she tells them. "The ingredients are still being mixed and you can make changes, but once it's baked in the oven for ten or twenty years, you’re pretty fixed on what you’ve done!"

Dr. Sills points out that the number one reason people avoid telling the truth is to avoid conflict. "It definitely works in the short run, but in the long run you never get to any real conflict resolution." She explains that any differences you may have with your partner need to be worked out with a degree of honesty and a little negotiating, and suggests that Kristen and Tyler separate the laundry into different baskets and each will responsible for cleaning whites or colors.

When it comes to details of their wedding planning, Tyler admits he often agrees with Kristen's decisions because he doesn't have a strong opinion and just wants to make her happy. Dr. Sills explains, "He’s basically saying, 'You’ve been thinking about the wedding since you were four, and I’ve been thinking about the wedding for the last 20 minutes after we got engaged. Honey, I want you to be happy.' That’s not a lie. Maybe he thinks, 'These aren’t my favorite flowers, but you’re my favorite girl.' That’s not a lie - that is love. That’s affection. That’s why we say, 'No, your butt doesn’t look big.' That’s love."

Dr. Sills' bottom line: "Do not lie to your spouse, but do love your spouse and tell the truth with gentleness."
