The main thing is to be close. Listen to her even if she is not immediately ready to talk. Sometimes you just need your presence, without words or advice.
Second, pay attention to detail. Give her her favorite flower or cook her favorite dish. It may seem small, but such gestures show you care.
Third, don’t forget about physical contact. Hugs, kisses, holding hands - all this creates a feeling of safety and support. Your love and understanding are the best medicine in difficult times. Every woman is unique, and the most important thing is to learn to understand exactly her needs. Did you know this? Have you encountered this? How did you react?
