Need advice to know if this girl likes me or not.

Hi, I hope my question get answered cause i been confused. First off, let me tell you that this has been going on for 5 months straight.

All right, here's the deal, I am in college and I get the feeling that this woman in my class likes me or is playing games with me, but I am not sure. Here is why I think this.

I really never noticed this woman until she started doing this.

She looks at me when I walk into the room.

There are a bunch of other guys in the class and the only one she looks at (I think) is me.

She started a random conversation with me out of nowhere with me one day. She asked what class I am taking, when do I finish, how long I have been taking it.

Her friends always smile at me when i am around them.

Out of all the places she sits in the class, she sits two rows in front of me where I can see her everyday.

She looks at me sometimes, the next day she ignores me, other days she looks at me and so on.

One time she was not in class for a week Her teacher was my practicum teacher. I went downstairt to look for him. I was talking to him and throughout the whole time I was talking to him, she was staring at me non stop and did not look away once. Basically she was standing working on a project the entire time I was there she was not at all working on that project.

I was out in the hall talking to a friend. Right in front of me is the door to go upstairs to class and right next to me is the hallway to go to class (but a longer way). Instead of taking the short way, she walks by me and decides to take the long way.

I got one of my women friends to talk to her and she came back and said that it was not gonna happen. I said cool, and I left it at that and moved on. But, then we have this.

I talked to her friend because I was setting her friend up with a future practicum interview becuase I know a person in her field. While I was talking to her friend, she was sitting there giving me this sheepish smile and has this day dreaming look in her eyes. I'm not sure but that is what it looks like.

Recently i have been talking to her but with random convos about school. I wished her a merry christmas one day when she left early. She says: "I am coming tom, say that to me tom", while smiling at me. I make a joke, she laughs before she leaves. The next day, I see her, but she walks right near me. (not 5 feet away from me or near my buddy who I was with at the time) She walks near me to the point where I can almost smell her hair, I say "can i say merry christmas now?" She says yes with a little grin. I say it she smiles. I go in the lounge to chill with my buddy, Her and her friend walk in and start talking. All of sudden all of us are talking. Here where it gets confusing. While I am talking to her, it seems that she wants me to say stuff to her. She is smiling but i don't know if she is into me. I heard it is playing hard to get, but when this happens it seems that she does not want to do anything with me.

Well here is where it gets a bit better or stranger (depending who read this), i got back from xmas break.She was not there for a week, 2nd week i found out she was in another class. One day i see her and decide to just say the hell with it and start talking to her. So i approach her and start talking. I stumble on my words a bit, say the same thing twice and somewhat say something that is not funny but she laughs anyway. But then she does a hair flip and starts smiling at me and has this coy relaxed look on her face. I realize i can't stop smiling like a buffon and we both are non stop smiling at each other. It was a crowd we were in but the whole time she was looking at me. Either that or she wanted to be nice.

So like i said before, i am very confused. What do you all think about this? Is she into me? and if she is why is she doing stuff that makes me think that she does not want anything to do with me.

Thank you, and I look foward to anybody's advice
