Make her understand that you worked hard for the money you earned.- If she asks you money for her family, take the matter seriously.For the plane ticket to Bali when you go on holidays?
If you are not ready to do that, and if she doesn't understand it as well, then you should find a Christian or Hindu girl, they make up 10% of the Indonesian people so it's not that hard to find.
- Even for small amounts, do not give the impressions that money isn't important for you.
Always show that the act of buying something is a rationale decision, not an impulsive one.
By going to less expensive restaurants, you give her the opportunity to treat you as well.
Religion: This is the second most important topic when dating an Indonesian girl because few of them will make a compromise about it.
