Please advise me on something!

Before the treatment, I had told my orthodontist that I will travel back to my country for 3 weeks for marriage proposals, and if he can take the braces off temporarily for that time period. He then said..yes, he will do that.
I am leaving to go back home on Nov 26, and returning on Dec 19.
In my last adjustment yesterday, I asked my ortho if he can take my braces off for 3 weeks from Nov 26 to Dec 19. He told me he does remember about committing to take braces off, BUT advised me NOT to take the braces off. His point was...my teeth just started moving nicely and if he takes braces off for one month....it will increase the total treatment time by 3-4 months. He said the braces do not look so bad and he would not advise taking them off at all. He reluctantly said he wil take braces off if I still want to take them off temporarily.

Now, I am in complete dilemma on what to do. I am not sure if I should take them off or travel back to home with braces. Actually I will first be attending a marriage...and then going to see my own marriage proposals. Obviously I am not comfortable having a smile with braces in a public function like marriage where you meet and talk to people every minute! But as per the ortho, his advise is to continue and not take the braces off!
PLEASE PLEASE advise me on what you guys think about it. My mind has completely stopped working on it..and desperately need to know what you people's opinions are. Thanks a ton for your support as always, and sorry for lengthy email!!!
