Abusers often use withholding, a cruel abusive technique where a person simply shuts up or stops communicating when a topic is not beneficial to them.
The abuser changes the subject of the conversation, not wanting to comment on anything about it.
This often happens when it is not beneficial for a person to take on a certain responsibility.

Any attempts you make to ask or negotiate to change the situation are ignored by the person.
How to Recognize an Abuser's Cruel Technique
Unexpected change of topic
When the interlocutor asks a question, he expects to receive a clear answer to it. The abuser may respond by changing the subject or ignoring the question.
Constant translation into a joke
In a conversation with an abuser, various topics arise, sometimes even very serious ones, but he does not react to them, preferring to make fun of them or discuss an inappropriate joke.
Putting off all decisions until later
Another withholding technique is when a person starts feeding his interlocutor with empty promises, but the problem is never resolved.
