So hello guys, i hope you can help me out with my problem. So i meet a girl, something like 3 months ago. Im in very strong love. But i don´t know she likes me.

About my self:
Im a 17 year old boy, my school is Technical college, and i work at a hypermarket. Im from Denmark.

You get the short story. So i met this girl at my work. I took my 30 min break, and went to the canteen. She was already sat in the canteen. I took some food, we have free bread etc. Then she began to ask me, that i will be at the work until it´s close. And i answered yes. So i took a seat, on an other table than she´s. I asked her about, that she was very busy at the work. She is at the cash desk. I refill products, at the hypermarket. She said it was fine. Then she stood op, and took a seat right in front of me, and smiled and looked at me, and she made the leg on leg position. She asked me out. School etc etc. And i found out that she is also going on Technical college, but on the other section and other adress than me. We have two Technical colleges sections. She also likes technology etc as me. Since that talk, i added her on facebook, and we writed to each other everyday. She always sending smiles to me, im also doing it to her. So there was a party, on her section of the school, and my section was invited. We talked only in one week. Via facebook. And 30 min in the break at my work. I enter that party with my class. I look for her, and when i finally see her, i make direct eye contact, she detects me. And she quickly says hello and she lays down on me and smiles. Then she moves and takes a seat. When we seated next to each other, she keeped touching me. She touched my leg, arm, almost my hand. She said im a good friend. So nothing more happend, the party ended i gave a hug to her and goodbye. So some days gone. And i invited her for a cofee. She paid for herself. And we talked much about different things. Then the strange thing is, her boyfriend called her, and i could hear, he asked where she was, and what she was doing. She did not say she was with me, she said that she was on the library, and she is coming back soon. We smiled much to each other, and we laughed of diffirent funny things. She bitched a bit about her boyfriend but no more. And we meet many times now in the canteen, and she always come to me and talk.

So what do you think guys about this? I really want to show her i like her? What can i do. I have plants to invite her for pizza, and i want to pay, but i don´t know she gonna want.
