There is a boy who always likes to say something ambiguous to me. Later, I didn't know what to say. What should I do?

In fact, you have discovered some bad habits of this boy, and some ambiguous words he said to you are probably just a means for him to please girls. It can be seen from your question that you don't hate him very much, but this kind of boy is a typical man who plays with feelings. Some ambiguous words he said to you are just an outlet for girls when he is lonely. Once you accept him, he will soon do you further harm.

My suggestion is not to reject him violently, which will make him hate you and get back at you. It's best to refuse him as a gentleman, no matter how he contacts you. As long as you give him a gentleman's smile and don't accept any of his invitations, you will lose interest in you for a long time and there will be no hatred. QQ is still accessible, and his messages will be ignored. You can reply to some strangers in words, and let them know from the bottom of your heart that you are not interested in him.

Does this analysis help you? You can leave me a message if you need any help.
