Hey all, hoping to hear some advice and how other writers deal with this kind of problem.
I feel like I'm fairly good at writing build up to romantic relationships, and enjoy doing so - the characters meeting, bonding, and eventually becoming a couple. However, I feel I have problems writing what comes next, such as in a sequel or something - I'm not sure how to develop a relationship after it's established.
I feel like I see a common trope in media where the first installment of a series will show the characters hooking up, but the second installment, now that they're together, is 90% of the time just making them have relationship problems. they fight, their relationship is on the line, maybe they break up, and then they apologize and hook up with each other at the end of the story. Rinse and repeat for any other sequels. While some dysfunctional couples can make sense and be well written, I feel like a lot of times this trope is used it's just a lazy rehashing of making the characters bond and fall in love again just like the first time, hitting the same notes instead of writing legitimately new development.
(please note I'm not saying having couples fight or break up is bad, just that I often see a cliche where this is a lazy rehash of what's already happened, instead of actually moving the relationship in new directions.)
I'd like to further develop relationships, but want to show a healthy relationship where the two involved mostly get along and are loving and supportive of each other with only minor issues. However, I'm not sure how to write this without it seeming boring. the only other option I feel I have is causing the two romantically involved characters to be mostly in separate locations or subplots through the story, so that while they get along, in practice they have little "screen time" together.
How do my fellow awesome writers handle writing relationships? How do you portray happy-but-realistic couples after they have gotten together and been with each other for a while without falling into cliche? Thanks for any tips!
TLDR not sure how to write happy couples, feel like I can only A) make them fight or be dysfunctional, or B) simply have the two characters not interact much with each other through the story
