This was a sweet ending to the Beautiful Bastard and the Bitch's story. Neither has changed except they love each other and planning the wedding becomes their crazy ride.
Their hate-love relationship is what keeps their love going. Fighting and making up is what Chloe and Bennett do best. Their wedding is not the exception. Except maybe Bennett's new rule before the wedding. That is definitely not the Bennett we love.
I'm glad that in the end everything worked out for them and now they are happily married.
