Those who refuse to love should decline politely

If you don't like the suitor and feel that there is no foundation for love, you can politely decline on the basis of respecting each other. You can tell him (her) how you feel and let him (her) understand that you only treat him (her) as a friend, a colleague or a brother and sister. You hope that your relationship can be maintained at this level. You don't want to hurt him (her) or tell others your secrets.

You can say some appropriate evasion and euphemism, such as: "I think our personality differences are too big, I'm afraid it's not appropriate." "You are a lovely girl, many people like you, you will find the right person."

"You are a good man. I respect you very much. Can we be friends forever?"

You can also find some appropriate excuses, such as: "my parents don't want me to fall in love so early, I don't want to hurt their heart."

If the other party is a person with strong self-esteem, he or she does not show his or her love directly, but only implicitly indicates his or her feelings in his or her words and deeds, then you can also take the same approach, use the language of implied refusal, and use appropriate indifference or alienation to let him or her understand your thoughts.
