Is unwarranted avoidance after reconciliation considered to be in the category of estranged individuals?

If the opponent's avoidance persists after reconciliation, it means that the reconciliation has not taken place and the estrangement continues, which is forbidden in Islam. One should initiate greetings to end the estrangement, for the better of two disputing parties is the one who initiates the greeting. If you initiate the greeting and the other person continues their estrangement, then the sin falls upon them, and the estrangement on your part is dissolved.
