I agree. I myself prefer shorter hair and think it would look great on you but if you don't like it then what's the point? You should feel comfortable with your hair as you'll be the one with it, not her.
Like everyone else has said its up to you. My boyfriend is growing his hair out for Locks Of Love again and it does grow on ya. After the 10 inches of hair has come, its gone and its back to short spikie hair.
