Building up Caroline

Caroline has flaws. She knows this. She's actually known this for a looooong time now. Some of the flaws are: she's too insecure, a sugar addict, a bit of a pushover, doesn't really give her body enough exercise and she is too careful when it comes to everything. All the mentioned flaws are a detrimental to herself and she wants to change. So she decided to so. Slowly she is starting to build herself up to the person who can confidently walk through life.

A think a want a to make this a romance story, but I want the heroine to be a flawed character that you kinda want to scream at once in awhile for making not so perfect choices, she is after all only human. I think I also want it to be a steamy romance with a hero that is kind of jerk.
