1. Manage your expectations.
"My parents always say relationships are all about communication and expectations."
2. Never assume, ask.
"My dad told me, 'never assume.' You will never really know what your partner wants unless you communicate"
3. Remember to always say "I love you" and "thank you."
"I've been married 21 years and we got married young — at 19 and 20. A couple things I think have helped us. Anytime we say goodbye, we always say, 'I love you'; and we make sure to thank the other for all the things we do. Like if he takes out the trash, I say 'thank you.' If I wash the dishes, he says 'thank you.' It just makes sure you never take the other for granted and they know it."
