I Need some GOOD Advice/Tips. Does She Like Me?

I broke up with my ex-girlfriend about 8 months ago. We are just good friends now. Well...I told her that I thought her cousin was pretty. It turns out...My ex told her cousin what I said! My ex said that her cousin got this ';He actually told YOU that?/I am flattered'; look on her face. ***Here is the funny part: Yesterday I got on myspace, and my Ex's cousin sent me a friend reqeust! The COUSIN sent me a friend request. Haha! So today I told my ex that her cousin sent me a friend request. My ex smiled and was kind of in disbelief. My ex said ';Wow....I can't believe she did that. That's funny!'; (BTW, my ex and I are really good friends and this isn't a revenge prank.) Tomorrow I see the cousin at church. When I see the cousin, what should I say to her? We've only barely talked in person before, and now she knows that I think she is pretty. What advice/words should I say to the cousin tomorrow? Should I just say hello and act friendly/flirty with her? Should I ask for her number too?I Need some GOOD Advice/Tips. Does She Like Me?
Just be cool. If you want her number ask for it.
