Search Results: reading a smile

In my class is this girl and guy (M.) and im friend wih both of them. She's sitting infront of me and we talk often. In the back of classroom is this guy who acts weird around her even he has girlfriend for 2 years.

She said to me that they won't say hi to her. They look at her and when she come close they ignore her. They don't hang out but she's really mad at them because of that. She said that when guys are not with M. they act normal to her. He doens't ignore her like she doesn't exist, he looks at her but never say a word. He was few times normal to her but mostly M. and his friend comment her, have their own "thing" about her.

It started when she borrowed M. something and this friend said to him her name across the room and they started to smiling.
He talks to her friend and act interested infront of her, but when she's not there he doesn't look at her friend even.
When are her friends with her they won't say even hi to them, but when she's not around they don't ignore them.
This guy, M. also often walks near her table and almost always kick her bag (only he).
They were making paper planes and trowing near us (me, her and 2 friends). They were joking with me, and then i heard that tM. said that someone is not looking. She was only one how could see them. When she would look only M. was facing her and he would run trough his hair with hand and look away or look away fast.
She was walking and reading message and stop next to table and there was a lot of space around her and in that moment M. walked near her (really close,) and she could feel him near her and turned and he was acting nothing happened.

I don't know what's really happening between tham. She's not hating him but also i don't know if she likes him and guys won't say anything.
