Hi Berry,
There is nothing to worry about. The usual flow is like this:
Mr XXX Ms YYY, am I to understand that you are here on your on free will (nobody forces you), for the purpose of becoming man and wife.
*Both reply YES*
Before you are joined in marriage, it is my duty here, to remind you of the solemn and binding character of the vows you are about to make.
Marriage according to Singapore law is the union of one man and one woman, voluntarily joined together with the exclusion of all other others.
*Face Each Other & Hold hands*
Mr XXX, do you take Ms YYY to be your wedded wife, to live together in the legal estate of matrimony.
*Reply YES I DO*
Will you solemnly promise that you will love her, comfort her, honour her and keep her in sickness and in health, forsaking all others, staying faithful to her, for as long as you both shall live.
*Reply YES I WILL*
