What does it mean for my boyfriend to say that I am an angel sent to him by heaven?

When your boyfriend says that you are an angel sent by God, he probably wants to express his love and gratitude to you, thinking that you have brought him warmth, protection and happiness. The metaphor of "little angel" vividly reflects your importance and mystery to him, and emotionally brings him a spiritual sustenance and dependence. Perhaps this kind of address will become a sweet nickname between you two, deepen your intimacy and emotional bond, and become a beautiful memory and emotional symbol in your relationship.
