At some point in your relationship, you're likely to get bored saying "good night" to your boyfriend or girlfriend. Think of an adorable phrase that she'll remember long after your next evening out comes to an end. Or, just text her that you'll be thinking of her until you meet again. Building a ritual by saying goodnight to each another can present an opportunity to bond and strengthen your relationship, says Margarita Tartakovsky, associate editor of Psych Central in the article, "5 Ways to Enhance Your Relationship Every Day."

Adorable Sayings

If you like music or movies, you can borrow lines from a song or movie to spice up your good night ritual. If you are still getting to know each other, say good night by saying something like, "I can't wait until the next time we're together. You keep me coming back for more. Until then." If you're in a serious relationship, try saying, "Right now, we must part, but very soon distance will no longer separate us at night. I love you."

Texting Good Night Until Tomorrow

Think of texting a cute message as a form of flirtation -- which can increase your desire to build a relationship, according to Sean M. Horan's article, "Why Do We Flirt?" published on Psychology Today. Text your guy before you drift off to let your boyfriend know he's your very last thought before you shut your eyes. Express good night in a romantic and cute way by texting your girlfriend sayings like, "Star light, star bright, you are the only star I see tonight. Sweet dreams."
