What does ending a letter with the word always mean?

Answer 1

'Always' is generally used when writing a lover or a good friend. EG: Always (or Always yours) Pat. It means you will always be their lover or friend.

This is never used in a business letter. 'Yours truly,' or 'Sincerely' are used.

Answer 2

It means like you'll always be theirs and stuff or like you have been always theirs and you'll always be or something like that.
