It's always best to feel fulfilled first, before finding a man. Then you'll know the value of yourself, and you'll hold the key to your own happiness. So you won't turn into a vulnerable, needy, emotional mess the minute you fall in love.
After he's gone Greer sits for a long time. She rests her head on her knees and weeps - not because she loved Blake and not because she's lost him. But because she did not care of herself. She knew Blake's nature the moment she met him, just as she knew the philandering fiancé. She knew them and she knew herself. Greer thinks of the story of the scorpion and the frog, and she knows she cannot blame these men for her messy life, they only did what she always knew they would do. No, this is not about crushed hopes and broken dreams. This is about trusting her own heart. Hope doesn't even enter into it.
