South Asian boy, 18.
Ok, I understand what you're worried about.
black tea is right to say that your happiness and wellbeing is paramount but I disagree with her that medicine isn't considered prestigious anymore. Sure, things have changed since the '80s, but most people and definitely most Asians view medicine with great value, and why wouldn't they - it's the ability to save peoples' lives, it's a beautiful thing?
However, you're clearly sure medicine isn't for you, and that's ok - it's not for everyone, and that doesn't make you less smart, if anything you have to be pretty smart to realise it's a good idea to get out of something which isn't for you whilst you can. There's no doubt some Asian parents will question it, but others won't. Plenty of them understand the difficulties with medicine now.
Overall, I think it comes down to what you do now. You've left medicine behind - fine - but what now? You need to find something that does work for you, so you can say 'I dropped out of med school because it wasn't for me but...I've since done xyz and am really happy'.
To answer your question directly, I would have no issue marrying a med school drop out, if she has done something of value since, and if she is happy now in herself. To be totally honest, I'd be grateful that I could see my wife more than 1 hour a day because she's not so exhausted (if she wanted to carry on working).
I hope this helps a bit. Ask anything else you want.
