The blind date chatted on qq for a week, and the chat was good, but he didn't ask me out except for a dinner. Is this normal?

I think it is normal. After all, we have only known each other for a week, and a meal delivery contact is just the beginning. Everyone will be embarrassed at first. If you want to have more contact opportunities, you can call him in two or three days, talk about your family, reveal where you want to play, or suggest what to do at the weekend. . . . Let him know you better. You are very cheerful. He will ask you out in a month. Love needs patience! Come on!
