<human>: Could you distill the essence of the text into 1-3 sentences?

There is this girl who I like. I met her during orientation at college. We hung out the first week. Then she completely isolated herself from everyone, including me. I asked her the reason for this later in that semester, she said that she was busy with her classes. 

She has a few friends. But I don't know who they are. 

We're in our sophomore year of college. She majors in Pharmacy and I in Engineering. So we never have any classes together. 

She is taking a physics class which I took in last fall. I told her that she could ask me for help anytime she wanted. All she said was,"Thanks a lot, I'll keep that in mind."

I seem to like her a lot. Ever since the day I met her. I did flirt with her a few times and do complement her every time I see her. She appreciates it and blushes a bit. 

She's never had a boyfriend before. And she's not dating anyone right now. I'm positive that she would not want to date me either. I asked her once if she was dating anyone; she simply said that she doesn't have the time for it. 

I asked her out to a football game. She turned me down by saying that she was busy. She said,"Maybe next time?"

We don't text much. We don't hang out much. I don't see her much. We dorm on campus. She lives a floor above me in the adjacent building. 

I want to tell her that I like her. It's not like we have a really good friendship that I would risk losing. But should I just tell her? I don't know. I feel that I should tell her how I feel about her.
<bot>: basically, I like this girl. Asked her out once, said no. The friendship isn't very strong. Should I just tell her that I like her, risking the small friendship?
