Friend of mine from Sri Lanka got married to a Polish lady. They lived happy many years and have few kids.
I think they did have good caring and understanding. They had exemplary life both visiting and kids following both traditional institutions and customs.
however lady steadily controlled the money and depleted savings and some investments for extravagant shopping and gambling. Bullying and controlling has caused considerable strain. It was a culture shock.
On a visit to her home country, I was told that she had no relatives and house was inhabitable. There were no water supply, running toilet, or bathroom or kitchen.
I hope people think carefully before committing.
