AFAIK the first requirement for divorce in Singapore is to be married for at least 3 years. But I think there are special cases, wherein a party can prove exceptional hardship, like when the spouse has been really cruel and there's domestic violence. It'd best to consult with a divorce lawyer. If you are in Singapore, I can recommend my friend's lawyer who handled a similar situation as yours -- Godwin Campos LLC. You can easily look them up and contact them through their website.
You can separate first while proceeding with the actual divorce. If it’s a mutual agreement, then it’s super easy. Just need both parties to sign and done!
