Commitment and concern for one another. Some call it love. Some people don't do relationships, some people need the comfort of waking up next to the same person every morning. Deep inside, the qualities we look for in a partner is something that cannot be defined... has nothing to do with gender, has nothing to do with physical or intellectual attraction.. it's just something that your soul recognizes. My view is that Love, when stripped of all its various associations, in its rawest unadulterated form, is simply an Understanding. Everyone wants to be understood.. love promotes the basic human instinct of survival.
