A few things here ....
First of all, the average filipino/filipina will 'reallocate' funds according to where the most urgent demand is coming from.
Secondly, it is not unusual in their the culture that a single filipina will give up her job (and move back home to parents, if she'd been living away) when a meaningful relationship starts.
Filipinas are tough - they will get by, somehow, with, or without, you - with, or without, your money. However, if the relationship is genuine, a filipina will be devoted to you for life.
I think that you are doing the right thing ... go back to see her again - a second visit can 'cement' a relationship. It won't necessarily remove all doubts, but it should bring you closer. I wish you both all the best.
