The Long Way Round (слэш)

“Maybe we shouldn’t see each other anymore,” Tony blurts out in a rush. “It’s—I think it’s for the best. If we stop.”
It takes a moment for the meaning of the words to register, but when it does, Bucky turns cold, stomach sinking. “Are—are you breakin’ up with me? Tony—”
“You didn’t do anything wrong,” Tony hurries to reassure, reading Bucky’s mind. “You were perfect, Bucky, I swear you were. Are. This. It’s not. It’s really not you,” he says with a small, humourless chuckle, “it’s me.”
Bucky looks at the tense line of Tony’s shoulders, at the sad set of his mouth, the defeat in his eyes, and he knows it’s the truth. Or, at least, what Tony believes to be true.
Or; sometimes, people mean well, but that doesn't always mean they know best. Bucky and Tony, unfortunately, have to learn that the hard way.
