Search Results: if a girl has very little experience

Soo there is this girl i met a few months ago. We have been texting now and then and at this point we have hugged/kissed (with tongue) . We have small talks everyday and some days we talk for like an hour, depends on her mood, my mood, the things we're talking about, you get it. Sadly we are not going to the same school. She still flirts back over text but she flirts a little bit less then in the beginning. Well... back to why I am asking this question... Every time when we are texting and it goes about hanging out together or doing something together she answers with a very open answer. Like: I'll let you know, i need to check if im free. She has never answered with a straight YES or NO. The first time (like 8/9 days ago) she said '' i 'll let you know'' and she did a few days later saying that she could'nt go out Friday with me, something about a school project ( My friend goes to that school and it was in fact a huge essay, so I believed her) . Now a week has passed and I asked her again, but this time I asked her to pick a date on which she was sure she could. She answered with : I need to check my schedule. I mean... in my experience that means she is not interested. I am at a point where I think she is trying to tell me in a subtle way she is not interested in me, to not hurt me or something like that.

So Girls/Guys what do you think... is she still interested? or nah?
