Let your partner know how much you love and appreciate them and understand their anxiety. Openly communicate how you feel about their clingy behavior and be specific about why it bothers you without casting blame. Support them as they struggle with their anxiety and encourage them to work on finding a greater sense of security within themselves while remaining firm in your boundaries. "It is tempting to try to reassure them enough that they stop feeling anxious and fearing rejection but that usually ends in frustration because the neediness and clinging is about how they experience themselves more than about the current relationship with you," adds Becker-Phelps.
