If a person cares about you, how long will it take for you to text her before she replies to you?

A person who cares about you will definitely reply to the message you sent immediately after seeing it. There is no doubt about this, but not all people who reply to you message instantly care about you. Maybe he will now Your son was looking at his phone and he responded to you right away. So to judge whether someone cares about you, you can’t just look at whether they reply to you in seconds. You have to make a comprehensive judgment based on other aspects.
