well, as long as she is not a psychoitc manipulative bitch (my old one was) she will feel like you are trusting her with a power to hurt you... so she will therefor feel more of a bond

if she is a psychotic manipulative bitch then she will play you and try to hurt you ... i made some worng chocies and she tried to hurt me...

but i dated her best friend and told her to F*uck off
