There could be several reasons why your boyfriend or ex acted like he didn't hear you:
Distraction: He might have been preoccupied with his own thoughts, emotions, or external stimuli, causing him to miss or not fully process what you said.
Emotional Shutdown: During heated discussions or arguments, some individuals may emotionally shut down as a defense mechanism. This could lead to them seeming like they are not hearing or acknowledging what you're saying.
Avoidance: If the topic of conversation was uncomfortable or triggered negative emotions, he may have intentionally avoided engaging in the conversation.
Communication Issues: Some people struggle with active listening and effective communication. It's possible that he didn't intend to ignore you but simply has difficulty processing and responding appropriately.
Selective Hearing: In some cases, people may choose to ignore certain topics or conversations they don't want to deal with or address.
Unresolved Issues: If there are unresolved issues between the two of you, he may find it challenging to engage in open communication, leading him to seemingly ignore or dismiss what you say.
Lack of Interest: It's unfortunate, but if he is no longer interested in the relationship or the conversation, he may appear indifferent and disengaged.
Defensiveness: If he feels attacked or criticized, he might respond by pretending not to hear in an attempt to protect himself emotionally.
Power Struggle: Some individuals engage in a power struggle within the relationship and may use ignoring or not listening as a way to gain control or show dominance.
Passive-Aggressive Behavior: Acting like he didn't hear you could be a passive-aggressive way to express displeasure or disagreement.
It's important to communicate openly and honestly about how his behavior makes you feel. If you're still in a relationship, addressing communication issues is vital for healthy and successful long-term connections. If he's an ex-partner, understanding the reasons behind such behavior can help you gain closure and move forward. However, if the behavior persists and affects your well-being, it may be a sign of deeper issues that could benefit from professional guidance or reevaluating the relationship altogether.
