Can texting patterns indicate attachment style?

Yes. Anxious folks text frequently and need quick responses. Avoidant folks text infrequently and take time responding. Secure folks text reliably but don't obsess. But patterns vary by context—you might be anxious with one partner and secure with another.

Is constant texting a sign of a healthy relationship?

Not necessarily. Constant texting can indicate anxiety or codependency. Healthy texting is consistent and responsive, but with healthy space. You don't need to be in contact 24/7. Quality > quantity.

How do I manage texting differences with my partner?

Negotiate: "I like a goodnight text. Does that work for you?" If they say yes and you never get it, that's a trust issue. If they're clear they can't do that, you know what to expect and can adjust. Clarity beats resentment.
