First post! Hi, everyone. So I'm writing a mystery series, and by the middle of the first book my main characters end up together after some tumultuous courting. They're in a very solid relationship from day one and I intend to keep it that way. They're going to go through some pretty rough shit throughout the series and I actually kind of need them to have each other. The thing I'm worried about is that people will find their strong relationship boring after a while. How do I make sure it doesn't get stale? And what are some good examples of characters that stay together in stories that aren't primarily romance fics? Thank you for answering!
