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!
