I was at a show/concert in toronto, I met her there, she bumped into me and said she was sorry, she stood beside me and asked what my name was, I told her, and she smiled really big and told me she had to leave to find her friend, and she asked for my number so we could hangout sometime. I texted her a day after and we talked for about a week, she asked me if I wanted to hangout so we hungout this Friday. We got coffee, hung around the mall but I'm just wondering if these were signs she was flirting with me, or if she wanted me to get the hell away from her lol.
When I first see her she had a huge smile on her face, said hi and gave me a big hug.
We would be walking beside each other and I'd see out of the corner of my eye she was looking at me and smiling.
Almost every chance she had she would try to playfully push me or hit my arm.
One point we had to look at a mall map because we were trying to find a coffee shop and she leaned up against me, and I put my arm around her and I looked down at her and seen her smiling really big.

I really really like her,
Even though it was my first time meeting her,
I'm not sure what I should do!
I'm pretty shy too lol :)

Whatever happened to this girl?

Oh well, relax guy and just enjoy hanging out. You seem to fall very easily for the females, but there is no hurry. You seem to like each other, so just hang out, and have fun.

Her actions you described seem to indicate an interest in you. Don't worry so much - just go with the flow. You don't have to interpret every smile or movement - just be yourself and have fun.
