Can I give him another chance?

I think this boy has feelings for you, but it's hard to say where this feeling is based. Because of his family, I think he is a very insecure person, and at the same time he belongs to the type of taking more than giving. Because of his indifference, he will try his best to ask for your love for him.

I agree with you that he is immature, because judging from his short messages, he has never understood why you are angry with him. He only knows that you are angry, but he doesn't know what he did wrong. I don't think he understands your feelings enough.

Although introduced by relatives, we haven't met formally. This is the biggest problem. Maybe two people communicate well on the Internet phone, but it doesn't mean that face-to-face communication can feel good. So I think you should stop studying his messages now and try to meet him. Two people will formally associate for a period of time in real life to see if they are suitable for each other.

The last sentence, just for a month, is about how much I love each other. I have never admired such a man.
