If your characters are underdeveloped, if you're rushing, if you're trying to cram a love story where one doesn't fit, you get an unrealistic romance that doesn't feel genuine. This can be the same for rivalry. I'm attempting to begin a long, complex relationship with multiple characters. One of these relationships will be a romance. I have a unique challenge, however, in that the romance will fall apart rather quickly. We all remember high school; dating someone and being infatuated with them, but after a certain amount of time, we no longer find interest in them, even despise them, and begin to wonder how we even liked them in the first place. Does anyone have any advice/ tips on doing this. The falling in "love" (more like lust I suppose, in this case) isn't what is the problem. I'm wondering what happens when the falling out begins. How do you go from thinking you like someone alot, to realizing you were never compatable in the first place?
