Mixed signals are not always a red flag, but they do mean you should stop reading only the best moments and start looking at the full pattern.
Mixed signals can come from hesitation, immaturity, low intent, uneven emotional availability, or simple inconsistency. The point is not to guess the exact reason too early, but to notice whether the pattern is improving or repeating.
A single good conversation means less than the overall pattern of initiative, consistency, follow-through, and whether the relationship is actually moving forward.
A relationship signal test is most useful when mixed signals are making your judgment noisy. It can help you separate hope, evidence, contradictions, and next-step decisions.
