Manipulation.

Narcissists love to quarrel on purpose, consciously, at the right time. This is an element of manipulation. Here are a few situations, the repetition of which should alert you. 1. For example, quarrels happen before giving gifts. Now, obviously, a person is not obliged to give you anything, and, as always, you are to blame. 2. A quarrel is arranged in order not to fulfill a promise. They promised you something, but they were not going to fulfill it. (I wanted to buy you, but because of your behavior and tantrums, I changed my mind.) 3. The narcissist creates a situation so that the victim does not leave to meet friends. Because ideally the victim should be isolated. After all, your entire life "should" revolve around the narcissist! Several fights and now the victim no longer wants to go hang out with friends. It is easier for her or him not to meet her friends than to relive this nightmare.
