One second a boy offered to share a joke with me, and the next he said, why don't you delete me? What do you mean?

The boy's behavior looks contradictory and confused. The following are several possible situations and explanations:

1. He may be joking, but he may drive too far, making you uncomfortable, or misunderstanding his real intention.

He may want to get your attention, but he may think you are not interested or unresponsive, so he gives up.

He may feel uneasy or uneasy for some reason, so he takes it out on you unintentionally.

In either case, if you are confused or uncomfortable about his behavior, you'd better communicate with him directly and ask him what's going on. This will not only clarify the misunderstanding, but also deepen the communication and understanding between you. In addition, if this boy's behavior makes you feel uncomfortable or uneasy, then you can consider keeping a certain distance to protect your feelings and safety. If he keeps acting unreliable or making you feel uncomfortable, then you can also consider ending this relationship. Don't let yourself fall into an unhealthy or unhappy relationship. It is very important to maintain your independence and sense of self-worth.
