We're vulnerable to repeating history, especially if we don't know what's driving us. For example, it may be a family tradition to marry someone with addiction problems, or who is an injured bird in need of caretaking. Or, you may be drawn to guys who remind you of your distant, unavailable father -- or your ill-tempered mother -- with the unconscious belief that you can take an old story, and through the power of your love, give it a new, happy ending.
