He began to talk 30 minutes ago and never stopped
I have known that adverb "never" is usually used in present tense with meaning that the action hasn't ever happened and will never happened, but does it have meaning " the action has not happened but may happen"?
Your sentence
He began to talk 30 minutes ago and never stopped.
only refers to the time in the past up to now, that the speaker has been talking continuously. He may or may not stop in the future, that is left unsaid.
It is equivalent to
He began to talk 30 minutes ago and has not stopped.
A popular phrase with the same construction is
She moved to the West Coast and hasn't looked back.
meaning she's never had second thoughts about moving to the West Coast.
