The best advice I've ever been given is being handed a Bible. That's the blueprint for marriage that we go by, and that's what our marriage is grounded in. We also have other married couples who are examples in our lives. My parents have been married over 40 years, and both sets of grandparents for over 65 years. When you see couples in long-term relationships and you see them go through good times and bad times, you realize it's about being committed enough and loving your partner enough to hang in there regardless.
