Ok I don't know where this goes so...(flirting question)

[derek12345]

There's this girl I sorta like (two actually) and I have quesitons about both of them.

 

The first time I thought "girl 1" was flirting with me was when she was smiling at me in the hall of school. She looked at me one time also in the school hall and was like "omg...". Than two years ago I had a class with her and these two annoying kids asked me something (so I gave a smart ass reply) and she told me just to tell them to **** off. She also slid her hand along where I sat on the table in the begining of class before she went to go sit down. Than last year we had a class together and she sat in the back of class and I sat in the front. She moved to the empty table right behind me (and told the teacher it was 'because she couldn't see'). She also kinda said "oh *my named here* should punch *his name in the face*. And she pointed her legs alot toward me and stuff. And smiled at me in the hallway again.

 

Girl 2: In an art class. She always told me where to get stuff. And she smiled and said "hi".

 

Girl 3: Asked me what I was doing for a project in class. Tries to "stand up" (don't ask) for me. Before she sat down she rubbed the spot on the table where I stand. Caught her staring at me in hall. Stood next to me when I was getting stuff from my locker. Has a boyfriend though (all 3 do actually).

 

Why would they do this when they have a boyfriend? Also it would help to know if they were really fliritng/and or like me.
