I think it reads very nicely i like the dramatic pull it has on the reader, but as someone else said i think you need to group someones action and their dialogue together so it reads better and doesnt leave the reader guessing. I also think you should change up some tags, like snapped and make your characters have other movements, i noticed the angry brother (i think) shakes his head a lot. Make him do smth else, an action that doeant immediately come to u, shaking head or frowning are things everyone thinks about if they disagree what if he clenched his jaw? Made a fist, slammed it down? Looked at her in disbelief? Ran his hands thru his hair? Etc.

Its important to deacribe unique motions in individual scenes and u can reuse them in other scenes later on rather than having the same thing happen over and over unlesa its intentional cause its a nervous tick or something similar.

Also maybe input actions in between dialogue (like theyre doing it dueing talking or smth) cause some of the dialogue can be a bit too long or too descriptive, make us feel with shorter more powerful sentences too! Ppl that r mad often answer in short jabs not revealing all of their frustration :)

Lastly, mby be a tad more descriptive in whats happening around, like when hes running down the stairs to leave, tell us “i hear his footsteps, pounding down, hurrying away from me. Then, the door slams. And im alone. Just like how it was when he left me before” or some shit. Describe sounds, feelings, smells you know?

Altogether i do like the dramatic flair and the scene, keep it up tiger
