<human>: Ok, so, there is this girl[17], not very attractive, let's call her Maria. We have been knowing each other for a long time (two years), and, as friends, we get along very well. I[18] always knew she was more or less interested in me (she behaved noticeably differently when I was around compared with other males), but I didn't feel anything for her, so I never tried to hit on her or something like that.         
      
Well, this morning she declared to me her feelings; she was super anxious and shy, but she found the courage to tell me everything. I tried to gently explain that I was very happy about that, but the her feeling for me wasn't mutual. In the end, I hugged her, trying to calm her down.         
   
The thing is that 5 or 6 days ago I met another girl, and I grew an enourmous crush on her. This new girl is beautiful; I can't stop thinking about her (I was thinking about asking her out one of those days).     
But now I have fear that I'm behaving like a huge asshole: Maria liked me for so much time, and I refuse her  only because I found a prettier girl (and I'm not even sure  she likes me!)....         
   
I don't know if I should try and go on a date with Maria, maybe I'll find out that she is the perfect girl for me. But if our relationship doesn't go anywhere, and I end up dumping her, wouldn't her feel much much worse?     
Maria has had very serious self-confidence problems, like cutting and continously crying, and that makes me very sad about this situation.

Can you give me the gist of the text in a nutshell?
<bot>: Girl asks me out, but I have a crush on another one. Fear of hurting her feelings.
