End vs Finish vs Be over (difference) I would like to know the difference in meaning between "to end", "to finish" and "to be over". I wonder if they mean the same and I can use them interchangeably. I have the following examples: 1. Elizabeth, I don't have a membership on this dating site. So, when the free messaging time ends, I won't be able to communicate with you anymore. 2. Elizabeth, I don't have a membership on this dating site. So, when the free messaging time finishes, I won't be able to communicate with you anymore. 3. Elizabeth, I don't have a membership on this dating site. So, when the free messaging time is over, I won't be able to communicate with you anymore. Are these examples correct? Do they sound natural?
