Ambiguity is a stage that people in love often go through, and in this stage, the most unpredictable thing is the sudden coldness of the other party. Some people say that this is the other party testing their sincerity, and some people say that this is the other party playing with their feelings. But in fact, the sudden coldness after the ambiguity is sometimes a "lore" in the love field. 
1. The coldness after the ambiguity can make both parties more certain of each other's feelingsAmbiguous, this word is full of ** and uncertainty, which makes people excited and confused. However, the coldness that follows the ambiguity may be a more profound way to confirm each other's feelings. In the ambiguous stage, both parties seem to be walking in the fog, unable to see each other's hearts, and can only grope with feelings. At this time, both sides are probing and speculating about each other's intentions. But this vague feeling can sometimes lead to misunderstandings or unnecessary confusion about feelings. However, when the ambiguity has passed, one of the parties suddenly becomes cold, which is like a clear signal that breaks the previous ambiguity. This sudden coldness will make the other party begin to reflect on their feelings. If the other partner feels lost or upset because of this, it means that he is serious about the relationship and he cares about the other party's reaction. This reaction just proves that he cares about the other party, and he wants to get confirmation and response from the other party. And if the other partner doesn't react to this coldness, it may indicate that he is not too committed to the relationship. Maybe he doesn't care so much about the other party's coldness, or he is a relatively cold person himself, and feelings are not so important to him. Therefore, the coldness after the ambiguity is actually a very subtle way to confirm each other's feelings. It's not as direct as a confession, but it's much more intimate. Because in this process, both parties will be more clear about their hearts and more certain of each other's feelings. 
Second, the coldness after the ambiguity is also the other party releasing their emotionsAmbiguity is one of the most intoxicating stages of love. At this stage, both parties are full of anticipation and uncertainty, each other's heartbeats are accelerating, and they are sensitive to each other's every subtle movement. However, after the ambiguity, sometimes there is a cold situation. This is actually the other party releasing their emotions. In the ambiguous phase, both sides are in a state of high tension. They crave a response from the other person, but fear that the response is not what they expect. This ambivalent state of mind can easily make people feel anxious and uneasy. Therefore, when one of the parties suddenly becomes cold, it is very likely that they are trying to adjust their emotions. In this case, the other party does not need to be too worried or nervous. Everyone has their own way of dealing with it, and some people need more time and space to process their emotions. You should respect the other person's choice, don't push them every step of the way, and don't put pressure on them. Give the other person some time and space to process their emotions on their own. When they adjust to their condition, they will naturally return to the relationship. Maybe they will face you with a more mature and stable mindset to make your relationship stronger. So, don't get discouraged by the other person's coldness, give them some time and space to handle their emotions on their own. 
Third, the coldness after the ambiguity is also the bottom line of the other party testing himselfThe coldness after the ambiguity may indeed be that the other party is testing his bottom line. In the relationship between the sexes, the ambiguous period is a critical stage, where both parties are groping and testing each other's bottom line and acceptance. This is a time when both parties are trying to get to know each other while also showing their charm and attractiveness. When one partner suddenly becomes cold, it could mean that he is testing the other side's reaction. He may want to see how the other person reacts when he retracts some of his enthusiasm a little. If the other person is able to stay calm and consistently show their charisma, it may mean that the other person has enough confidence and maturity to handle the situation. However, if the other party is upset by the change or begins to show obvious loss and dissatisfaction, then the lukewarm party may test further to see if the other party is really a good fit for them. This process of indifference and testing is actually a process of mutual understanding and running-in between the two sides. But it's worth noting that everyone reacts and copes differently. Some people may feel that this is disrespectful or hurtful and choose to end the relationship. Others, on the other hand, choose to communicate and understand, trying to adapt to each other. In general, the coldness after the ambiguity is the other party's bottom line testing, but this does not mean that the relationship will necessarily be ruined. The key is how both sides respond and deal with the situation. The sudden coldness after the ambiguity is not a bad thing, sometimes it is a "lore" in the love field. Don't be overly excited or anxious when faced with the other person's coldness. Calmly analyze the situation and see what the other person is cold about and whether this coldness is justified. Of course, love is not the whole of life, maintain your independence and sense of self-worth, so as not to let yourself be trapped in such tangled emotions.
Don't be too demanding and persistent, blindly force and persistent, face the feelings that are not suitable, learn to let go appropriately, and make each other more relaxed.
