Before anyone embarks on a relationship as a male, it is best to consider WHAT the female expects, regardless if local & worse-foreign women whom grew up in hardship. She does not open up herself (& her private self) for charity. The conditions are female expectations, not necessarily both -
A)money to open her up as she knows like any human that without money in life, nothing can be done.
B)The more altruistic women - she wants a faithful companion for life, to unconditionally love her when her looks get faded, the way her parents had loved her, thru ups & downs as Humanity's sacred vows of marriage had been ordained for centuries.
You already need all the encouragement you want. It came from within yourself. You only want validation from others. Sadly, from others whom had been burnt badly in relationships, local or foreign, there will be no validation of such, but only to be pragmatic, be cynical.
As we Humans are 3 dimensional beings, not most would had been evolved into the 4th dimension-time - to see consequences , & there are further dimensions in life which is yet unknown at this current stage of evolution of Humankind.
But the greatest dimension that exists in our universe is LOVE. It is only thru love that the gift of LIFE is given, exists, & compels one to achieve beyond limits - to provide, to progress & evolve, a meaning to life.
Love is a power, & often misunderstood with lust, & thus most got burnt. To truly love is to set someone free, not caged them like a bird. Such is only possession, with expectations of worldly returns & emotions. We are only Humans, & thus your predicament - to trust her or not.
The most important element in a relationship is trust. If you do not trust her now, & with valid reasons, then there is no point in having a relationship at all. Just grow old, live in a fantasy world of women who only want your money & not you as a person, wither in loneliness & pass on, hopefully at least with enough CPF in your account to at least take care of the passing, & hope you need not beg for a living when you are too old & frail to take care of yourself with no kids.
No Human is perfect. It will be her actions that will prove trust to you, & equally, she too will put you to the test, just as you did her with her expectations. She had proven to you that she is not money minded, cared not for sweet talking others whom promised her the stars & moon. She is not stupid, more so in her line where she gets such promises every night, & warned by her colleagues that such men will only dump her once they get want they lustily want.
No mortal can change the past. But we still can change the future. Based upon what you had written, she desires a better future for herself & her family, & loved you which is the most important factor. She may continue in her line if you cannot financially support her & her family, let's be realistic in expectations, but it will be you that her gift of life belongs, not her DNA body.
No man likes to be cuckold, but there is NO man on Earth that pines for the LOVE of a woman unconditionally - her soul, the way we men were loved by our parents. Rich men can only posses bodies, never the heart...
However, encouraging as it may seems, do take into considerations:-
1) We have to be pragmatic - are you ready to commit to her, come hell or high water, for life, thru the ups & downs in life, in hardships, emotional turmoil & financial?
2)Can you overcome her past, as no one is perfect & build upon the relationship to a higher level, beyond lust, for a love that will be eternal - to both your future generations to come?
If not, walk away. If you are ready, then I wish you all the best, to a fulfilling & meaningful journey in life than the emptiness & loneliness of those whom dared not try to truly love.
