As someone who has always shed any serious relationship for fear that I would end up drowning in a sea of contempt, chained to the anchor of responsibility for others, I can tell you that if you choose an unknown future, it will be what you shape it into. Being alone can at times be lonely, but the wings of personal freedom can carry the weight of regret. Listen to your heart, and have belief that your future is yours to shape. Whatever you decide to do, fill your life with positive, healthy thoughts, actions, and people. Your world is a reflection of what you put into the world.
