That will be great 👍, can't wait to read your book.

So building gradually on your story will really produce a masterpiece, avoid overthinking the end and just flow with the storyline as it unfolds in your mind

B. Thriller: in this context the partner who decided not to move on abducts every partner the other person has or even in the worst case murders them, then blackmail the other partner into thinking he or she killed them and get them to be together again however short lived because the truth leaked.

3. Like I said the genre will determine how the storyline will go. Two possible contexts.
A. Comedy: the partner trying to get back tries everything possible to paint or portray the new found partner as incompetent, finding faults and ensuring that he/she flops at almost everything humourously.

Hello Lyam, it's actually going to be interesting you just have to consider the context in which you want to write about. Take for example
1. The couple are they married or on courtship?
2. The genre will determine how the next context goes ( who moved on and is the other trying to get back again)
