Is it normal to text someone once a day?
Depends.It depends
Yes, texting someone once a day is normal for plenty of people. Whether it feels right depends on your relationship, your communication styles, and whether the effort feels mutual.
Some people like a daily check-in; others would rather text less and catch up properly later. Neither style is automatically a sign of being clingy or uninterested.
Pay attention to whether the other person seems comfortable and engaged, rather than treating a daily text as a rule. If you’re the only one keeping the conversation going, it may be worth easing up or asking what kind of communication works for them.
