Why do people tend to engage in self-denial after a breakup?

After most people experience a breakup, they tend to fall into severe self-doubt and self-denial. They constantly feel that it is their lack of excellence, lack of consideration, and inability to manage relationships that led the other person to leave. They magnify their own shortcomings and get trapped in negative emotions such as self-abasement, anxiety, and depression.
This kind of mentality is a normal emotional misconception after a breakup. The core of an ending relationship is mostly about mutual adjustment in interaction, compatibility of values, and rhythm mismatch, and it is never a one-sided lack of quality. However, after a breakup, people’s emotions are sensitive, and they subconsciously attribute all the faults to themselves.
Long-term self-denial can severely undermine one’s sense of self-worth, making them become self-abased, sensitive, timid, and weak. It not only fails to heal the breakup but also affects daily life, social interactions, and subsequent emotional attitudes. They are afraid to make another commitment and dare not easily fall in love.
True acceptance is to objectively view the outcome of the breakup. Relationships are about fate and compatibility. Separation is merely that both parties are not suitable for each other, not that you are not excellent. Accepting the regret and affirming oneself, letting go of self-harm and self-denial, can help one break through the gloom and embrace a confident self again.
