I really really like her, does she like me in all seriousness, females only. . . . .?

im 15, im from scotland, i met this girl 2 weeks ago and i absolutly adore her, we talked alot on facebook and we went to party on saturday, i took her aside from a group of friends and looked right in her eyes (scared as hell btw! ) and said " i think your beautiful and im starting to like you " she called me very cute and the sweetest guy shes ever met, ill see her on friday, how should i act towards her ? and when im with her. she said to my best mate that she would kiss me but she doesnt know if she would go out with me cos she dont know me that well,, ( also, does she like it when i start all the conversations, because it makes me feel like an actual stalker, although we go on to have very good conversations.) should i ask her to go on walk or something to just talk ?can i have long answers, i appriciate it. thanks x
