I hope that my response will prove to be of some assistance to you.
It is evident that you have been hurt in this relationship. You feel that your heart has become cold and that you can no longer trust others. You are uncertain about the circumstances surrounding this situation. One effective method for processing your emotions is to write down your feelings and thoughts. This can help to clarify your thoughts and relieve your emotions. Once you have written, you may feel more comfortable. Given the lack of detailed information about your experience, I can only provide some general ideas for your consideration.
What are the underlying thoughts and psychological needs that contribute to this emotional state?
In such instances, it is important to identify the specific thoughts that arise in the mind. Are these thoughts related to recollections of hurtful statements made by the other person? Do these statements elicit a sense of agreement, leading to feelings of doubt or self-denial, even to the point of self-attack?
Do you experience feelings of self-reproach and doubt your self-worth? Do you feel indignant and believe that the other person should not treat you in this manner, but rather in a manner that aligns with your expectations?
...
It is important to note that the comments and words in question do not represent the truth. If the individual in question is causing the individual to feel uncomfortable, it is possible to respond to the comments by stating that they are not true. It is essential to examine the underlying causes of negative emotions and feelings of detachment. These emotions may be the result of unmet psychological needs.
Indeed, negative emotions are indicative of unmet psychological needs, which, in turn, contribute to a sense of overall unhappiness.
One might inquire whether the individual who has caused distress is capable of providing the desired outcome.
Is the need for support and affirmation being expressed, or is the desire for comfort and encouragement more evident?
One must inquire as to whether companionship and trust are still required, and whether this person is capable of providing the desired support.
Does he demonstrate proficiency in providing support and encouragement to others? Is it plausible that he not only fails to offer these things to you, but also to other individuals and even to himself?
In the absence of desire and the inability of the other person to provide what is desired, the result is suffering due to the lack of fulfillment.
It is, in fact, typical for individuals to have needs. However, it is crucial to identify the individuals who can provide the necessary support, understanding, care, and trust. Only through this process can individuals receive the nourishment and support they require in their relationships. These individuals are worthy of one's trust and belief.
3. It is necessary to be selective in one's social interactions, to evaluate one's relationships, to make certain compromises, and to utilize healthy relationships as a means of "detoxifying" unhealthy ones.
Mr. Zeng Qifeng has previously stated that "people are social animals. The more relationships one has, the more nourishment one receives, and the faster and better one grows." He further elaborates that a nourishing relationship should be one that is full of trust and friendship, and one that gives both love and freedom.
As a person develops a greater number of nourishing and loving relationships, they become increasingly bold in their pursuit of happiness and success.
It is evident that relationships are a necessity in life; however, it is crucial to recognize that not all relationships are equally beneficial. The formation of nourishing and healthy relationships is of paramount importance. It is not necessary to trust everyone, nor is it feasible to maintain positive relationships with everyone. The ability to discern between those who can provide genuine understanding and support and those who are detrimental is essential. It is therefore prudent to prioritize time with individuals who can offer nourishment and support, while limiting interactions with those who are draining. This approach can lead to an increase in happiness.

I understand that feeling, it's like the warmth just fades away when you're by yourself, and trusting others becomes this huge challenge. It's tough to open up when you feel so distant from everyone.
Sometimes in solitude, I also feel my heart turning cold, and it's hard not to be skeptical of people's intentions. It's as if every wall I build gets a little higher, keeping me from getting too close to anyone.
It's such a strange sensation, being alone and feeling your heart chill. I find myself withdrawing, becoming indifferent because it feels safer than risking getting hurt again.
Feeling my heart grow cold in silence is something I've experienced too. It's like the ability to trust just slips away, and all that's left is this apathy towards the world around me.
When I'm on my own, I often feel an overwhelming sense of coldness in my heart. Trusting others seems like a distant memory, and I end up feeling quite indifferent to what's happening around me.
