What does my girlfriend mean?

Im sorry for what you found out, but shake her hand? That is funny dude. What you do is kiss her like you never kissed her before and show her what kind of man you are. Tell her how much you want to be with her and you sincerely apologize again for your sly ways. Okay, you found out something but you've got to take the horse by the reins now and prove to her that you are worthy. Be your own man and seduce this woman.
