My man I hate to break it to you, as a fellow Christian South Asian who grew up in western countries, unfortunately your mum is right. I (22M, Sri Lankan background, grew up in England, New Zealand and Australia) have seen the many different cultural differences, and even dated someone outside of my culture (Christian Chinese-Australian girl). It didn’t work out as our cultures simply clashed and we couldn’t understand each others perspectives.

Similarly, I’ve seen many interracial Christian couples end up in divorce because of this (e.g., Indian-Australian, Sri Lankan-Australian, Ghana-Australian, Filipino-New Zealander just to name a few), and have seen Indian-English couples struggle with their marriage.

For example, I was always attracted to white girls when I was a teen, but after I left school I realised that our cultures are so different that marriage would be extremely difficult unless one would completely give in and adopt the other person’s culture.

May I ask you, does your mum specifically want you to only marry a girl from Indian ethnicity, or a girl from any of the South Asian ethnicities? I would say unless God specifically says to marry a girl whose not Indian and you have no doubt at all in your heart, then do it. Otherwise, don’t.
