Wise words from the wonderful Thich Nhat Hanh in How to Love.
When a loved one is suffering a lot, he or she doesn’t have enough energy to embrace you and help you to suffer less. So it’s natural that you become disappointed. You think that the other person’s presence is no longer helpful to you. You may even wonder if you love this person anymore. If you’re patient and you practice taking care of yourself and the other person, you may have a chance to discover that the elements of goodness and beauty in the person you love are still there. Taking care of yourself, you can support your loved one and reestablish the joy in your relationship.
