This was perhaps the best of these short tomes to heartbreak I've read from you. I really liked the beginning, You dabble in cliché quite a bit, which can be difficult to execute. The "roller coaster of emotion" phrasing was really weak, but you bounced back from it. But I do think you'd be better off working to develop your own set of images and turns of phrases instead of working in such trodden ground. You're good at starting off verses well, perhaps because you usually keep things straightforward instead of burying yourself in metaphors that build on each other. The penultimate line bothered me because "we can both be" needs a plural object ("better people" instead of "a better person"), and I think that's one of those instances where even non-grammar nerds would fumble with the phrasing. But your rhymes are consistent and well-patterend, giving you a really natural cadence.
I'm hoping you will be back for Season 3 of the Art of Writing League, which I'll be running starting in about two weeks. Obviously, your personal life interfered, which is completely understandable and worth offering condolences for, but you had a strong run going at the start of Season 2.
Also, if you have time, Split Eight and I would appreciate a vote on our Battle Arena topical match:
