"better" or "best"?

Dear Fellow Members:

Patricia: Why the long face?
James: Mona has left me for another dude.
Patricia: Don’t be sad, Jimmy. Maybe it’s for the _____.
James: How?
Patricia: Mona was a horrible cook. Now is your chance to meet someone who can cook well.

Would you use “better” or “best”?

Why?

Thank you,

James

‘for the best’ is the correct idiomatic expression.
