Both keep you on a string, but for different reasons. Benching ranks you — you are a reserve to be called up if better options fall through. Breadcrumbing feeds you just enough attention to keep the response coming, with no ranking implied.

Benching
Benching is keeping someone on the sidelines as a low-priority option — enough texts, likes and vague plans to keep them interested, but never advancing to a real relationship, while you keep other prospects in play. Outside dating, benching is the plainer thing the slang borrows from: pulling someone out of active play on a team.
Breadcrumbing is when someone gives you just enough attention — a like, a flirty text, a “miss you” — to keep you interested, without ever intending to commit or meet. A trail of crumbs that leads nowhere.
