left someone hanging

Never followed through

To leave someone hanging is to abandon them in a state of suspense or uncertainty, typically by failing to respond, follow through, or provide expected information.

Someone left hanging awaits a reply, decision, or resolution that never comes: I asked if she wanted to grab dinner and she left me hanging for three days.

The image is of someone dangling mid-air, unsupported—vulnerable and unable to proceed.
