Barty wasn't the type to run back to their exes. No, far from it. He usually cut all contact and pretended they never existed in the first place. Which was a questionable technique, but it is what it is.
So when your fireplace lit up green and Barty fell out of it, you were surprised, to say the least. You two broke up almost three months ago, and since then it has been radio silence. Which was fine. It's not like he broke up with you out of the blue and just left you in bed alone.
"Hey," he coughed. "Sorry to be a bother," he said, stumbling onto his feet. You could see the blood running from his nose and a gash across his eyebrow. A fresh bruise was about to turn purple on his right cheek.
"It happened again, and I just- I didn't know where to go," Barty stifled a sob. You were the only one of his exes who knew about his father's abuse. Maybe you were the only one to ever know that.
