I have known blind date girls for almost 1 month, and I have met them four times. 1-2 days can I send a message? Do you need to send messages every day?

You are not going on a blind date, you are going to make friends.

According to your practice, it will end in vain, because your relationship will not make any progress, so it is not far away, and there is no fire, just waiting for one party to give up.

Blind date is purposeful communication, which makes you feel good and walk into (the other person's) life to see if it is appropriate. If you send a text message for a few days or two, it will be different from you.
