Does she like me and should I try again?? help?

So in 10th grade I went to the homecoming with this girl and afterward I asked her to be my girl friend. Which was a bad idea because we barely knew each other. And it was awkward but I had no sense. So now two years later we start hanging out like outta no where with friends an today we hung out all day just the two of us. We went to lunch and chilled all day. I kept spotting her up and would like hold hands for a second or two over and over. Then I put my head on her shoulder for a second and she didn't move away and we kept getting really close. I like her still. She does call me dude sometimes if that means Anything. But she just seems like she likes me. I need help
