Keep and follow through on commitments you make. Be consistent. Listen empathetically, be present with your partner, and ask questions to better understand them and your relationship with them. Continually deepen your own self-awareness so that you can share your most honest thoughts, emotions, needs, and requests.
You cannot love without trusting a person. As mentioned earlier, trust is the building block of love. Just like how a child trusts her mother and thereby loves her, your partner needs to know that you are trustworthy and won’t ditch them in difficult times. This feeling is important for love to sprout and flourish.
