10. Respect your partner, and don’t take him or her for granted.

Treating your sweetheart with respect is likely to get you the same in return. And regularly reminding them how much they mean to you will enrich your relationship in indescribable ways. When you say, “I love you,” pause for a moment to really mean it. And don’t be afraid to express your feelings of appreciation with your partner — he or she will be thankful that you did.
