story idea

Ok, so I thought of a potential story idea. It is actually a story I started over the summer before fanfic took over my life. I really didn't like what I had so I will re-work it.
The main character is Sue, married with 2 kids. Her best friend is Lori, a single girl that likes to have fun. (Kind of an opposites attrack thing going on). Anyway. Lori starts dating Kasey who she really likes and he kind of changes her ways (a little). Kasey really likes Lori and shows up a the apartment a lot but Lori is never home. Sue ends up going through a divorce and Kasey is more then willing to help her cope. You can see where this is leading.
I'm not really sure on any more major points after that. I tend to let the story unfold without me really knowing anything. Not the best way to write but it is usually how I do it. My inspiration is my best friend. She is awesome and always has an interesting story to tell me about one of her many "guy friends". I'm going to have to give her a call to get some more dirt, lol.
That is pretty much all I have right now. Just 15 days until hell begins.
