Karla and Terry are a happy couple in Nebraska -- they've been married for years.
She's an associate professor and he's in insurance. They have children, and grandchildren -- and they've been happily married for 38 years.
So, what is the secret to their success?
They only live together on weekends.
Yes, you read that right. Because of their jobs, one lives in Lincoln, and the other in Omaha. Instead of commuting two hours each way -- every day -- they live separately during the week.
Her advice: People may judge you, but as long as it works for you and your husband, that's all that matters.
