Mabele, you said it...
Its really no easy decision. Thanks for your help
... but if you made your savings and you don't want to rock the boat and because you lining in the SE Asia, then Singapore. I'm assuming you are in India or Sri Lanka.
Singapore is a very multi-cultural island-state where loads of SE Asians live along with the majority of Chinese (75%). It's nice and clean, expensive (where isn't of the major world cities?), low profile, good for families (kids despite education expenses) and loads of places to go to within a 2 hour flight. Tropical weather. I'm sure you are used to it by now. Good luck!
