Another online date? Wow...do keep us inform if you succeed...

but frankly speaking, knowing some1 thru online, and only met her twice, love at first sight, that might not lead to long-lasting love if thats what you are looking for...
Before you embarked onto a r/s, know the person well first. Her hobbies, interests, even her friends and family and background hor..dun jump into it just because she looks pleasant or chio..haha..

If she really turns down yr dates, probably its a hint to you? Or she thinks that its too fast too furious, so you should take it slower?
Try again with a milder sms like "hows your day?" instead of " wana go out dinner?" Keep that for a while, maintain contacts thru your whatever online means, and maybe she will open up more to you about her complicated r/s. From then, talk n talk n talk..wait for opportunity to strike...
good luck dude!
