Was it Love Or Illusion..

There is a question in my life I cant find an answer to... May be you people can help me...
I don't even know where to begin but this is all started when he first met her. A simple, sweet guy with a huge smile on his face and dat too came when she entered the room. A girl with a calm and shy face, lots of expression was there on her face at a time. I think she was a bit nervous and excited too. She came in to the room and just then this guys came by her side and said "Hi!". She replied nicely and took her seat. I don't know if he noticed it or not but I did, everytime he turned his face to her, a smile came on her face. He was so indulge in himself and his work that he couldn't notice that smile and shine on that girls's face. days passed by and they became good friends. She started to see a new place coming up in her life for that boy. People started to blabber lots of things about both of them.
As usual, when you are right, you don't care about the world. I heard someone saying dat " Don't care about what people talk about you, but do care about what you give them to talk." Well both of them were so involved in each other that they were unaware of the world, they found new friends in each other.

One day after classes, i saw the guy rushing towards the girl. He came to her and told her all about his feeling for her. He was so in love, i can still feel dat. The warmth of every single words coming from his heart, was so real. He was so into her that was not able to think about something else at that time. Even the girl was madly in love with this guy, he was her world, her life, her heartbeat, her everything.

But one thing which hurted me most and I found it strange, was, that they both were in love,the guy did pour out his heart to the girl.... but as few days passed on he suddenly started acting strange.
One day when the girl couldn't take it any-more she went to the guy and asked him where does she stand in his life. He didn't reply to her. He said nothing and left. Was it so neccessary to leave it unspoken? or Is it so mutual to even express? I didn't understand that time.

Days passed, the girl waited for her answer. She wanted to know all about his feelings but he was not ready to say a single word. After some time I found out that this guy with calm face and cute smile, was already in love with someone else and couldn't break that other girl's heart. And the sudden expression of the feelings of this first girl, put him in a wierd situation. Neither he wanted to hurt any of them nor he wanted to loose any of them.
I cant understand.... is it possible to love 2 people at the same time and was it love actually??
I still don't know.

He didn't came to attend his classes for the next 2-3 days. During those missing days, I missed that shining smile on the girls face. I silently watched each and everything, taking place between them. I don't know about others present in that room, but I was surely the eye witness of their friendship, love, sorrow and every other emotion.

After 2-3 days, the guy came to the class. He looked silent and calm as usual. The girl was sitting at the corner of the room silently but I saw a strange change in her mood. She looked so desperate to talk to him. I saw the feelings in her eyes like she wanted to hold him in her arms and never let him go any where.
At the mean time I saw the sorry feelings in the boy's eyes like he was blaming himself for whatever happened to this girl without even knowing the reason. But he had planned something else for her. He came near her and held her hands. She looked surprised or rather say shocked. He holded his hand up and said " I don't want you to go. I want you to be with me forever." and tear rolled down his cheek. She was suprised by what he just said and in anticipation she hugged him tightly and cried her heart out like she way saying " Don't worry swetheart, I am not going anywhere. I'll be by your side." With this sweet girl, i was crying too...I don't know why..

Time passed, they started talking and treating each other like they are so in love with each other, but at every prospect the guy compares this girl to that other girl whom he loves. Now at this point, he was in love with two people at the same time.
Was he loyal to any of them?

Was he really in love with any of them or both of them?

I left the classes and the story as well. I dont' know the end and my questions left unanswered. I don't know if I ever get to know the end or the answers, but one thing which I know is , they both cared a lot for each other and there was some thing more than just freindship.

I don't know what it was Illusion or Love, doesn't matter, but there was something....
