Worse than being left on open. They are definitely avoiding you, They can’t evn be bothered to open your text! Usaly can tell if it says they are still active on social media or have done other things eg. Post on story, text in group chat.
If you are left on delivered for a hour or more It definitely means that the person hates you and just want you to go away .
You can definitely die from being left on delivered as it causes a extreme heart disease
