My friend is lovelorn and I don't know how to comfort her.

In this case, you have a correct idea. Nowadays, people can't tell the difference between dogs and people. If she doesn't realize herself, he will be hurt even more in the future. If it were me, I would stimulate her and say that when you are with him, I will tell you that this man is not serious. You didn't listen, and now you deserve it. A man can't even tell others about the woman he likes. He loves you. He's just playing with your own feelings. You are still silly to cry for him. Are you worth it? Be strong, leave your tears to those who love you the most, and give your smile to those who hurt you. It is his regret in this life to prove with strength that he doesn't cherish you. . . . . . . . . Thank you, I hope to accept the answer.
