You are considerate, empathetic, and compassionate - and who doesn't need a little more of those qualities in their life? You want to encase a partner in a protective shell of comfort and security, and feel just as nurtured by him or her.
If you know that you belong to another, as well as to a location and a loyal group of friends and/or relatives, you are content.
Your caution is to take care that the mothering doesn't turn into smothering. You want to embrace another gently, not cling for dear life.
