How to keep a Shenyang woman?

There's this woman I have met from social romance tours I attended to. This Shenyang woman didn't just capture my eyes, but also my heart. We have known each other for three months now and we went out just twice. She's very difficult to please and to find. She already tested my patience but I don't have a choice since I like her. I have to make a move so she won't slip away. What should I do?
