Life is about movement, expansion, growth, and actualizing potential. If you stay in a home, relationship, or job beyond the time it is healthy for you, the universe will prod you with thorns as if to say, “It’s time to move to a broader domain.” If you do not heed the message, the thorns will get sharper and at some point you will have no choice but to fly. When you do, you will understand why a once comfortable situation became uncomfortable.
The point of life is not to be married or single - it is to be. We are human beings, or humans being. It does not matter so much what lifestyle we choose - it's what we make of the opportunities to grow, that counts.
