TS, she is not wrong. What is the reason to be together when the other half always not around ? You are suppose to journey this life together if you plan to get married. If the other half can do all the thing on his/her own, the relationship or the marriage has no meaning at all. Either one of you need to compromise.

My prediction, it will not work if you don't have intention to come back to Malaysia or she have no intention to go to Singapore. Unless you have plan to work at Singapore for a short term & will eventually come back. However, based on my observation so far, 10 out of 10 ppl going to Singapore, non of them coming back to Malaysia because the currency exchange / earning power. Once you are used to Singapore working environment, your growth & network will be based on Singapore, it will become even harder for you to come back.

If neither one of you can compromise, see thing in the girl's angle. Don't hold her back coz her youth limited, it will be best to let her go.
