A blind date met a boy. He chatted with me and said that he wanted me to be his girlfriend. I didn't promise him directly, just said to get to know him better first. He told me that day.

He wants you to be his girlfriend. You tell him that you can get to know him first, which means you like him.

When you say you can get to know him first, you are actually euphemistically giving him a chance to associate with you, not as a boyfriend and girlfriend. Although you associate as friends, the feeling between you is different from that of ordinary friends.

But he didn't realize it. He thought when you said get to know each other first, you meant to refuse him. He thinks you don't know each other well enough, so we can be friends. He thought you sent him a friend card.

He hasn't contacted you for a few days. He may be really busy, or he may be too busy contacting other women to call you.

That's my analysis, not necessarily right.
