Does it mean that the relationship is over if you stop talking to each other but never say its over?

Not necessarily; a lack of communication can indicate problems in a relationship, but it doesn't automatically mean it's over. Sometimes, individuals may need space or time to process their feelings before addressing the relationship's status. However, prolonged silence can lead to misunderstandings and assumptions, so it's essential to have an open conversation if both parties are willing to clarify their feelings and intentions.
