@joyokiyi,
You should understand that there are various levels of communication both in and outside marriage.
There are three levels of communication, namely:
1. Cliche (just complementries, greetings)
2. Fact (Sharing what you know,exposing nothing about yourself)
3. Opinion (Your idea about things,you reveal little about yourself cautiously)
4. Emotion (Gut-level communication, emotional communication)
5. Transperency (Being completely open with the other person)
For more on these i'll recommend this book for your friend "Starting Your Marriage Right" by Dennis & Barbara Rainey. I read it and i can tell you i gained a lot from it.
Wish you happiness in your marriage.
Ciao
