Tell the boy that I miss him. What does he mean by inviting me to dinner next time?

You tell that boy that you miss him. Besides, the boy said to invite you to dinner next time. Personally, I think that boys want to let you know that you are not suitable by eating. He doesn't want to hurt you, he wants to find a chance to tell you. He may have someone he likes. He wants you to face the problem frankly and sincerely. He doesn't want to refuse directly, and he doesn't want to be silent. He is looking for the right opportunity, but he wants to let you go, but he is persistent. So I said I'd invite you to dinner next time.
