Is the phrase "take good care of yourself" really hurtful?

It's not hurtful, it's sad, and it's the object of discussion.

Let’s talk about friends first. After the college entrance examination, I made an appointment to meet a very good friend in a place. We originally agreed on a city, but unfortunately her score was too bad and she went to a far away place. We are very ordinary. After eating and shopping for a while, I bought her a Q-coin recharge card. It was like coaxing a child. She preferred to play games. Then when she left, she told me that you have to take care of yourself. We all need to take good care of ourselves. of. I immediately felt like crying. She was very good at writing articles. She always said such literary sentences, making her life feel like a novel. But I felt very moved, and besides being moved, there was also a sadness of separation. After all, it is a feast that will eventually come to an end.

If a boyfriend and girlfriend say this, it shouldn’t be a hurtful feeling in a precise sense, but a sigh that things are different and people are different, and they are helpless that this relationship has come to an end. , this is mostly the case, and it does not rule out that one party is going on a business trip, and it is normal for the other party to say, take good care of yourself there. But it was hypocritical to say this when we were breaking up. I was really comforted like this. When I heard this, I kept crying and crying, thinking about staying and not breaking up, but in the end I held it back because I felt it was hypocritical. I felt that everyone who said this was not sincere. At this time, You should stop being pretentious, either simply and rudely not saying a word, or trying to stay, or saying harsh words. Do you say such words in the hope that the other person will still think of you after breaking up? What is this if it's not scum? Don't feel hurt, you should go back with a good sarcasm. No matter how much you sigh or how helpless or reluctant you are, don't look back. From now on, it is best to walk on both sides of the road and never meet each other for the rest of your life.
