Worth the Work?

I don't like putting myself out there (where ever there is.)  i don't like giving you my heart. i don't like telling you my stories. i don't like letting you learn my body. i don't like feeling weak. Either i wait for the man that's willing to wait out my crazy or i become a nun... i do like the color black.... i need help on this. how do you know when the person is worth your heart and soul?
