Hi guys, I want to ask for opinion. My friend (24F) is dating a Bangladeshi (25M)

My friend (24F) is dating a Bangladeshi (25M), his nationality still Bangladesh and they plan to get married. Relationship : less than a year. My friend is crazy marriage girl, like she is obsessed with wedding or being a housewife. She left her current bf at that time for this Bangladeshi man. This man was aware too that at that time, she has a bf. I actually dislike this man not because of his race but because he openly told my friend when she was still dating her current bf that my friend deserve to be in a relationship with 2 guys at the same time (him) and at that time current bf. However, he is a Muslim and she is a Christian. She doesn't want to convert to Muslim, and he doesn't want to convert to Non-Muslim (I don't know if it is legal In Bangladesh - Please educate me) I told her in Malaysia, it is not gonna work. She said if they have children she is willing to register herself as a single parent mom. I don't know how great is this Bangladeshi man that she is wiling to do that. Of course, I against it, willing to risk herself being abandoned by a man with KIDS, without any legal agreement ties. And she said that they will get married in Thailand, under his recommendation, I said it doesn't matter, getting married anywhere, still the marriage certificate would not be legalized in Malaysia. And then, after a few months, he said that they can get married in Bangladesh, Bangladesh support cross marriage, I was wondering why he wasn't being transparent at first. But nvm, so, She said she wanted to get married in Bangladesh, without converting of course (I don't know if cross marriage between Muslim and Christian is LEGAL in Bangladesh - anyone who knows please educate me ) but doesn't want to live there either, she wants to reside in Malaysia.
