[color=red]1-He won’t help you again.
[color=indigo]2-He won’t help you, again.
Is there a difference between the meanings of the above sentences? I think 1 means:
[color=darkblue]a-He has helped you in the past or is helping you now but he won’t do it again.
and 2 means:
[color=darkblue]b-Once again, he won’t help you.
Is that correct?
