If a girl is interested in you, she will never, and I mean, NEVER ask you up front whether you have a crush on her, if at all.
The one thing you must understand is that girls are never direct or straightforward with the guys they like. In your case, it is obvious that you have been showing her too many hints that you are crushing on her pretty bad.
And if she asks you the question, it just means that she has been suspecting this for a long time, and confirmed this with your confession. In my opinion, you have lost this game, and now your “crushing” fate is all up to her mercy. You fell right into her bait; she may now choose what to do with you however she wishes.
Even if she likes you back just a little bit, does not mean that she is willing to be tgt with you. Girls require a lot more than mere “crushes” to be in a relationship with someone.
Hell, even if a girl hates you to the core, she may still want to be together with you if you do the game right —> Now this is why a lot of girls end up with abusive boyfriends.
The number one rule in dating game is never, never ever confess your feeling to the opposite sex.
Whoever confess first, basically admit defeat and resigned their fate to the other’s hands. I can go on and on about what you can do, and should have done but anyway a lot of ppl are probably going disagree with me; besides, everyone has their own relationship journey. So I wish you luck with yours and take this post with a pinch of salt. Hopefully I am wrong and you will have closed the deal in the next few weeks. 
OR better, just move on and find a new target cuz this girl is just going to play the long game with you. It’s not worth the time. Singapore is small but not that small.
Tl;dr: gg bro.
