Need help for a friend.

You tell them they better change their mind or the relationship is finished.

Relationships don't last long term if there is no communication.

no communication=no relationship.

Since they refuse to communicate send them a card saying, "It's over."

This satisfies the non-communication barrier and ends a pathetic relationship.

You move on.

You say they don't want to communicate.

You can't talk to a wall.. move on.

A relationship will not last without communication.
