My ex-girlfriend suddenly sent me a text message asking me to take good care of myself. What should I do?

Hello, now that we have broken up, move on. There is a saying that I won't envy you if you have a good life after breaking up, and I won't bless you if you have a bad life. Maybe parting is for a better start for the next paragraph. Fate will be together, and if there is fate, it can't be separated. If he no longer contacts you, then you should put it down and seek your own happiness, so that you will be happy.
