I said this earlier.
So you know this but still trying to be a knight in shining armor? Divorce her before she does you. Let her and her kids struggle. The father of those kids did it. Why should you be the one fixing a broken pipe?
And do you feel good when someone tells you they married you out of pity?
Plan a trip to the Philippines for everyone. When you get there, leave them, pass by Thailand, enjoy all you can and then back to US for you. She can't come back because she doesn't have GC nor AP.
You must be feeling that you scored some young hot Filipina whom you can't let go, despite all the mistreatment. In a few months after she gets her GC and leave you for whoever currently waiting behind the curtains, you'll be back here asking us how to deport her.
Man, there's something wrong with you. I'm Mike-E-ing. I can't.
