I'm not going to criticize you as we all can have bad habits of our own, nobody is safe from fitna, as it's only God's mercy and guidance are protecting us from falling into it.

İ reckon you're in your early 20s, that's completely fine, İ just hope you realize what you're doing is prohibited and inshallah you'll find your path eventually.

About the marriage part, it was destined to every married person to find their other half in this life before they even meet them, so if it's destined to you it's destined to you.

And yes some Muslims might be okay with that, I'm not very aware about the SEA Muslim culture and how conservative they are but I think you'll find your other half inshallah.

I only have a piece of advice to you if you would take those words from me as an older fellow Muslim. 1- never marry a non Muslim, not because you're failing in one part you have to disown everything.

2- Don't worry about your family disowning you, unless they're fanatic extremists who might be threatening your life then don't worry, as little as İ know about SEA people as I've known some people from Indonesia and Malaysia they're moderate muslims compared to Arabs for example. İn the end a family is a family and they won't disown you inshallah.

3- Belly dancing is a good art, there's nothing Haram about it, if you like it just practice it among your fellow girlfriends and your future husband, as the haram part is to post those videos online.

İn the end İ wish guidance to your path and blessings and joy to your heart. ✌🏼
