I'm going to jump in here. Not sure if this will be helpful or not.
After my wife got here, also from the Philippines, she went thru a period of time where she acted similar to this. She was physically and mentally abusive to me, all the while screaming I was abusive to her when I would never even consider laying a hand on her. (Don't EVER do that, because then it's ALL on you.) She got jealous over things that happened only in her dreams. (You ever get yelled at for something that happened in someone's dream? And asked to apologize for it? I did!) She kept threatening to "go home" or to "go to a Philippine shelter". (Someone told her they exist). At one point, after being physically assaulted, I called the police. Since I had a mark on me and she didn't have anything, the police were going to charge her with abuse. I declined, but that stuff stopped quickly. She told me she was a bit shocked that in the USA they would charge a woman with abuse. Sometime (maybe before, or after) she called some Philippine "mission" and they told her they had nothing to do with people's marriages. (I still don't know who she called, but it was weird) After that, one of our Philippine neighbors essentially told her to cut it out. (On these last items, I didn't have to do anything, the stars just aligned in our favor)
She subsequently got a job that she absolutely loves. She's turned around. She's NEVER physically abusive anymore. Occasionally she's emotionally abusive(?) or maybe manipulative, but she's gotten so much better with that, and we are at the point now where I can go "hey, you are doing that again." I've had my faults too (aren't we all a work in progress?), but we've grown together thru this process.
Consider this: Her voyage here was crazy for her from a mental standpoint. She's left her whole world behind. She is alone, except for with you. She's about as far away from home as she can get. Don't underestimate what that does to any person, especially one that has likely never traveled outside of her country. She's transitioning from a long distance relationship to being a full time wife and partner. That doesn't excuse the threats or the abuse. In fact, I'd recommend asking her to go to therapy together, so a third party can help you find methods to work thru these things. Many Filipinas have insane level jealously issues, even when unjustified. She may need therapy to learn to deal with those feelings, which likely drive some of her behavior.
Now many have said abusers never change. That's often true. But it's not 100% true. It wasn't for me. My wife and I are once again crazy mad in love with each other, and I can't think of not wanting to spend the rest of my life with her. For the first year or so after she got here, it was pure hell. But now, it's nice. She's back to being the girl I fell in love with when I was living in Manila. Our relationship is stronger than ever. I hope this same outcome for you.
You have been given a lot of really great perspectives here. I hope you find a solution that works for you, and I wish you the very best.
