I am not gonna lie, there seems to be nothing good in this story.
To ME, and I could be wrong saying this, but it sounds like you wanted her isolated and 100% dependent on you for everything. She has no money because you don't let her have access to it. She wants to drive but you don't want her to. She is a new resident of a new country and all she is allowed to experience of it is what you allow her to. You refer to her as "my Filipina" like she is a possession or a pet and not a wife. You cannot expect someone in this situation not to feel more like an inmate than a spouse.
When you were texting her and you admitted to hitting her, did she also in text admit that she pushed/covered your face pushed your face? I am no expert, but as soon as one person admits to the police they got physical, the handcuffs go on. The situation she is in, I don't blame her for using whatever means necessary to get out of the relationship, just as you are willing to ship her back to the Philippines to never be seen again. You are using the purse strings to control the situation, she is going to use your domestic violence transgression to get things to go her way.
Here is my opinion. I don't think this is salvageable. If she wants to stay here, all of the dominoes are in her favor and she will stay and you will pay, that is not in doubt. The only way I see this working out for you in any way is if she wants to return to the Philippines and give up on life in the US. If she goes back home and her situation is good there then maybe she wont go after you financially. You have brought up finances quite a bit, so if that is your concern, the life she will have in the Philippines will be a lot cheaper for you to handle than the life she is going to have in the US.
