I might understand, or I might not. I'm really not interested in girlfriends or anything like that.
But of course she would never be the same. No person is the same. But I suggest that you wait for another girl. You may find someone right for you in a few days, a few months, or maybe a few years. But you will find someone eventually. Just don't bother Samantha. Doing things like the petition thing can make girls angry. If she doesn't want to be with you, then she doesn't want to be with you and there's really nothing you can do about it. It's the truth.
