I had a co-worker who went this route. The girl from the Philippines was 22 years younger than him. I'm retired now and I often wonder if he is still married.
He is a good guy and has a heart of gold. I just hope she realized that by now.
I had a co-worker who thought he was going to marry a bar girl in Korea. He moved there from here, and it wasn't long before we heard he was in love.
Long story short, he paid her "bar debt", which was over $10K -- maybe much more. Who knows how much he spent on her leading up to that. Once she was free of the debt, she moved to another town and started working at another bar -- I assume she got a windfall (new debt) from the other bar when she started working.
Never reconciled whether I pitied him or lost respect for him. He was a very smart guy, but somehow he lost his mind when she entered his life. The dude was probably 350 lbs when I met him. I saw pictures from 3 years earlier when he first moved to Hawaii. He had a knock-down gorgeous GF, and he was maybe 180 lbs. He gained all that weight living here. I assume his weight made him think he couldn't get another woman, so he was easy to take advantage of.
Last time I saw him a few years later I didn't recognize him. He looked 150 lbs lighter. I heard he had surgery to drop the weight.
It's safer to be single sometimes -- just sayin'.
