I have the hardest time and am most attracted to the girls that are just sooo nice. always smiling and being friendly, but i dont know what to do with this type because what ever rapport breaking i do during the conversation and show im interested she dodges it in the nicest way and still continues to chat with me.

Yesterday, i met this girl from ecuador who came for vacation to the states. She was incredibly nice. i was walking with her and some friends into the woods. luckily her and i got lost from the group and were in the middle of no where. we sat down at a big rock with a nice view and started chatting. she gave me a few IOIs and i needed to break rapport. i asked her what she looked for in a guy. how good she kisses from 1 to 10. then asked if she were lost in the woods with a guy she just met and the guy asked for a kiss after such a good conversation would she accept? she smiled and said, "it depends" i didnt ask her on what and instead said, "what if i asked to kiss you?" she said "no I wouldnt" with a flirty smile. I said why not? she said, "because i have a boyfriend and i want to respect him". after this i wanted to ask "and if you didnt have a boyfriend?" But it was too late the group of friends had found us.

What did i do wrong? I dont know how to break rapport with a super nice girl any advice?
