Please answer, i need help!!!!!?

Hey guys, well the sadies dance i was supposed to go with this girl got cancelled. wasnt sad at all since there is another girl that will straight out try to disrupt our dance and make our time miserable. Well, toay, i felt bad so i went to talk to her sinc ei knew about it yesterday and didnt message her about it. I forgot or something came up. She felt overwhelmed of the fact that i was considerate enough to tell her that. So she asked me if i still wanted to go out with her on friday since the dance was cancelled. She just popped the question. So my question is wether this girl likes me and should i go? Oh yah, the background info is that she liked me before but we never actually got together so we came to a conclusion that we shall just stay as friends. I recently about a week ago heard from my friends and her where we all volunteer at the hospital that he heard her saying that she still likes me and that she should have never stop liking me. I really do like her. I never noticed it after she started too. It was this thing. I never felt like this about any other girl. She is really beautiful and smart!!! Sorry for the long details but should i go with her and if so does this mean she likes me? Because she was able to ask me to go out even though the dance was cancelled. Please answer as much as possible. Thank You
