Some men need a Princess Charming. Some men don't know how to love the way you need him to. Maybe he's scared of rejection, of being laughed at, of doing it wrong. Maybe he tried once or twice or a hundred times, before you, with you, and it ended in a disaster that he's unable to recover from.
Or maybe he just doesn't know.
You can help him. Show him. You can be to him what you want him to be to you. Submit yourself to being the woman HE needs. To help him defeat his fears and help him become the man he longs to be.
I don't know one decent man that doesn't want to be a good husband.
