And the bummer thing is, ghosts never leave. They might leave you alone sometimes, but they're always there deep down, whispering lies in your ear. They echo the lies others told you: That you're not smart enough; that you're not pretty; that you'll never amount to anything.
If you've treated your girlfriend without respect, taken advantage of her, or cheated on her, your actions have taught her that she has no value. Needless to say, this is a serious, serious injury. If you don't try to make it right, she might start to believe the lie you've told her and spend the rest of her life thinking she deserves poor treatment.
