What is crush is hot and cold?

A crush being hot and cold refers to their behavior towards the person who likes them. They may demonstrate interest and flirtation one moment and then pull back and be distant or unresponsive the next. This can be confusing for the person with the crush, as they may not know how to interpret the mixed signals. It could be a sign that the crush is unsure about their feelings, playing games, or trying to keep their options open. In any case, it can be frustrating and emotionally taxing for the person on the receiving end of this behavior.
