I'm sorry this happened to you. I've read too many stories like this and honestly, they dug for the gold and didn't get it so it's time to leave the mine.
My husband and I started poor - I came to the US, he didn't have a high paying job and we budgeted everything to the last penny. I got my green card about 6 months later and started working, we've both grown and able to somewhat be stable. We bought a house, brand new vehicles, and fund some fun stuff like a little bit of travelling - that being said, I NEVER SUPPORTED MY FAMILY IN THE PHILIPPINES - my family back home isn't rich. My mom relies on her retirement and my brother only has very few online gigs here and there but I made it clear I will not enable toxic culture of relying on the one who got a good job, or works abroad, or married a foreign man. I absolutely made it clear I will not support them because I came here to build MY own family so until we are in a good financial position, I'm not going to send large amounts of money.
Thankfully, my mom is understanding and not a show off. She didn't boast about money and my extended family aren't asking for anything. One time someone did and I immediately turned it down. I did what my husband did when our relationship started - he made it clear that he wasn't rich and he will not be supporting the whole town because he's American which I completely understand. I give my mom some assistance every now and then, and occasional balikbayan boxes but there is no expectations.
You can't generalize all Filipinas as we're all different but I'm not going to deny that the expectation to provide for everyone is there. It's something to always watch out for. I hate how some turn this into a business of getting a foreign spouse as a means to an end, because at the end of the day we're all judged just the same.
