I'm writing a short story. It's about two lovers who meet sometime later in their lives and talk about the old days. But, it's hard to delve substantially into their history unless I write a novel about it, which I'm not. The piece is only about 7,000 words long. My question is should I even bother with flashbacks? My theory is that if I can't develop their past relationship enough, maybe I shouldn't bother going there in the first place, since it will just come across as shallow. Maybe I should just let their current feelings for each other sustain the story. But I'm not sure what to do. I know it's hard for you to help me unless you've actually read the story I've written, but I figured maybe some of you would have some similar experiences.
