Filing annulment against wife who is Financially irresponsible, has numerous debts due to missusing and mishandling of the money I am sending.

I am married and working abroad, solely providing for the family. Although my wife is capacitated to work she refuses to do so as she claims she is taking care of the kids. We are paying someone to help her look after the kids so she cannot claim she is the only one taking care of the kids. She does not work, I am the sole provider yet she is financially irresponsible. 

We are on the verge of separating due to her excessive lies regarding money. I am sending a sum of almost 100,000.00 Philippine pesos to her every month but she keeps saying that it’s not enough. We only have 2 kids, not yet attending school. We do not pay rent/mortgage because we have our own house but she's always short. Not long ago I learned that she has numerous debts without my knowledge. Now she is insinuating that she wants to leave, taking the kids. What legal way and rights do I hold on the situation? 

I don't want her to bring the kids as I believe she is not doing well and fit, cannot able to think properly, and is not financially capable of supporting and taking care of the kids. She cannot say she is busy taking care of the kids because I'm paying someone else to assist and help her so she cannot say she’s the sole responsible. I want to know what my rights are. I treated her very well. They have their separate budget for her everyday food bought from outside as she complains that she doesn't know how to cook herself. 

We have been married for six years, and in those six years, there have been numerous instances where we fought/argued about her misusing and mishandling money. I have documented everything. There are instances where she got scammed "according" to her resulting to a loss of 30k PHP, and another scenario where she was scammed for over 40,000 which she also lied about. There are many times she hides where the money is going. I have been working for 2 years now. We do not even have a single cent of savings because I am sending almost all of my salary. 

I stayed and believed she would change but now that I have learned all about her secret debts, which she later revealed as I have talked to every single person she has debts. She has admitted lying and tampering, misusing the money herself. Whenever I raise the issue, she will get mad and put the blame on me instead. Obviously, she is manipulating me as she is very good at that. I reached my limit. I now want to rest my case. 

I am currently paying for her accumulated debts and suffering Financial, Emotional, and Mental distress. It is Financial Abuse of my wife, her being deceitful regarding her huge spending resulting in numerous debts she's been hiding from me, to the point the she will use the money I am sending for support to pay for her debts, instead of spending it to the kids, she's spending it to her personal and unnecessary expenses. She's been tampering with the lists of budgets and receipts to prove she is not misusing and mishandling the money I am sending to support her and my Children. 

I am nothing but a good, considerate, husband and Father to my Children and what I experienced now is traumatic. I cannot be able to trust her again since even when we were not married yet, she has been displaying a behavior that shows she doesn't know how to control herself from misusing her money. Could all of these be a ground for Annulment and getting the custody of the Children? Does her being Narcissist, Financially Irresponsible, and Financially deceptive can be the reason that falls under Fraud or Psychological Incapacity? I want to make sure now that the money I am working hard for will only go straight to my Children.
