Mixed signals are actually one very clear signal: they aren’t sure, and you deserve someone who is.

Uncertainty is itself a position. When someone alternates between interest and distance, nothing is being hidden, it is simply a message you would rather not receive, which is that they have not decided. Waiting for clarity means waiting for them to change, and that may not happen. In the meantime the ambiguity is costing you something real.

Give this a period and a limit rather than an open-ended wait. Ask once, plainly, what they want. Whatever comes back, treat an unwillingness to answer as an answer of its own.
