Teenage Love Problems?

There's this girl I really like, I don't want to say I love her yet because I've only been talking to her for a few months. All my friends told me not to talk to her because she was NOT going to have . But I didn't care because I liked her for her. Well when I was out of town her and a really good friend of mines were dating, I knew this, but I didn't know her. So when I moved back in town they had broken up and I started talking to her on FB, she gave me her number and started calling me hun, and saying things like awww when I called her beautiful. So we got together for a date, and I chilled over her house. After the date things changed, she would still text me but I always had to text first, and she never said things like awww or called me hun anymore. She started sending one word text messages more often, and when I called her beautiful she just said thanks. It's like she put me in the friend zone. So then I made a bold move and said I miss you, she then said me too. That made me feel really good considering I like her soooo much. So the a few days later, (she still was sending one word text) I said I missed he and she said ditto. Again that made me feel good. Then she went out of town recently, and while she was in the car I was texting her and I was like I miss you and she was just like Oh. That kind of Hurt. But while she was on the road she found out that I knew the her ex (my friend) and she said I shouldn't even like her anymore b/c he's my friend. I told her that I wasn't here when they talked and him being her ex isn't going to change they way I feel about her. And she said it didn't matter to her b/c it's my friend. So i asked her if she still had feelings for him she said yea a little bit. Then I asked if she had anyfeelings towards me, she told me she looks at me as more of a friend :( I asked her if it could go further and she said she really thinks we should be strictly friends. But the thing is I want to be more than friends with this girl. Help
