What is the mentality of having an affair with an ex-girlfriend after breaking up?

People are always nostalgic. People who really loved each other will never forget, at least not completely, even if they break up. They may forget slowly with the passage of time, and only think of her casually at some special times, thinking of the past days. Personally, don't be too close friends after breaking up. If we break up peacefully, we can be ordinary friends who say hello occasionally. Pay attention to just ordinary friends. Let bygones be bygones. Time is gone, and nothing can come back. People should look forward and don't dwell on the past, otherwise you will stand still and be unable to pursue future happiness, especially if you have a new girlfriend. Think of the past as your precious memory. Why do girls care about your ex-girlfriend Because they love you and don't love you, who cares about your past, and have never met anyone who really loves you. The above are personal opinions and are for reference only. Please accept it if you are satisfied. Have a nice day.
