Giving verbal affection, such as saying, “I love you” or “I care about you”, is an important way to strengthen bonds and is even good for you physically and mentally.  Don’t let texting or emailing the ones you love replace verbal affection. If you are apart, then pick up the phone to check in because it’s more personal, even if it takes more time.  Verbal expressions of affection are the words you speak intended to validate your positive feelings of love and affection and make your partner feel loved. This can be unique to you, your partner and your relationship as long as what you say produces the intended emotions and reinforces your affection for each other. If you must use electronic modes of communication, sign off with a phrase like “Thinking of you” or “Miss you” instead of a something generic. Since you won’t be able to physically touch and bolster your bond that way, you will need to tell him or her how you feel more often. This is important to maintain the closeness in your relationship and reinforce feelings of safety, comfort and trust. If possible, use Skype or Google Hangout so you can make eye contact and pick up on physical cues while talking.

This can be anything from the way they look, a feature of their face that you particularly enjoy (such as eyes or lips), a personality trait, accomplishments, the positive way they make you feel or a skillset that you admire. Be honest, and don’t let opportunities to compliment those you love pass you by. Tell your wife, “You have beautiful eyes” while looking at her or “You complete me”, if it’s true. Tell your husband, “You look handsome...

TL;DR in Vietnamese:
Đưa ra lời khẳng định. Hiểu rằng các mối quan hệ ở cách xa nhau đều cần phải có nhiều lời nói yêu thương. Khen ngợi người mà bạn quan tâm mỗi ngày. Chào đón khi người bạn đời hay con cái trở về đến nhà. Đặt biệt danh cho vợ/chồng hay con của bạn. Dành thời gian để nói lời “Cảm ơn”. Đừng cho rằng “Em yêu anh” là cách duy nhất để bày tỏ yêu thương.
