Saying 'Congrats' Would be Hypocritical

my best friend just emailed me and told me she's getting married...i don't know how to respond! 

for years she's been telling me she'd be better off without him and that she was getting rid of him but they always make up.  she knows he's no good for her but i know there's no changing her mind. 

i want to be happy for her but i know it's a mistake and now i don't know what to say...congratulations would be hypocritical.  please advise!  thanks
