I don't know where to go with this little piece I'm writing, advice?

Maybe the guy is like holding out on her because he turns out to be something really major like a criminal or married to another women or something. If he was a criminal he might be involved with a crime that this lady has to cover him for and then the plot thickens? So far it's like a bit predictable. It needs some action or glamour to make it better. Something bigger than just a romance.
