Love advice for a mid highschooler?

Ok so at the start of this school year there was this girl who really liked me but i didnt like her we talked a little but i never was "in love" it eventually got to the point where i would try my best to avoid her, her friends were always like "dude your hurting her" but i didnt care so then for a while it was quiet i stopped seeing her or getting messages i was kind of happy till one day i happened to see her and i fell instantly to the deepest pits of love i tried to find her after school but couldnt find her so i sent her a text telling about how i felt and how i really liked her and was stupid and blind before and shes like "oh i know" and so i expressed how i would like to get to know her but she said she dont like me anymore....it was like a slap i took it all cool and like yeah thats cool thanks any ways kind of aditude after that when i start seeing her in school i would talk to her a bit but one night i just broke down and sent a text to her how deeply i felt for her and she didnt reply. We continued to talk here and there in school but it was never close until lastnight i been thinking about her so i sent her a text and we started talking random i made mention how i was glad i was able to make her laugh she said of course later on i expresed how i wish i could see her and she replied with this funky art thing that said "love you" so i replied with one that said love you more and she said i love you very much and i replied i love you to infinity then she said she missed me (we have been out of school for a while) and i said i missed her too then she said she had drawn a picture of me and i said that was sweet this was like at 2:00 in the morning and we said good night. I really was in love but now im starting to wonder if i really do and if just aint an somthing in my mind. Please tell me what you think of my sictuation and if this is good bad, should we　go out?
