Wat does this mean,is this love?

I know a senior of my college thru net,once i joined i never spoke to him but we used to look at each other in the college,he used to look at me as a close person looks at me.As time pes by i got attracted to him only bcz of his studies and his thoughts(i used to look at his blog and orkut profile regularly),one day when there was a cultural fest in our college i was searching for me(as i said i was attracted) he observed me looking at him and immediately took his frnds and from the next day on he used to come with his frnds to my mess just look at him after few days i mailed him for a help then thanked him for that(talked almost after a month),from the next day on he used to behave though as he loves me very much ,used to look at me .One day we juniors gave a farewell party to seniors ,in that party during foto session all his frnds pointed me out on the stage and teased me tat being a girl i look at him ,listening to all this he could not resist them but laughed to their comments,in that party he behaved sarcastically and me feel low,i felt very bad and wrote in my blog that i never loved anyone(but he is still in my heart),he knew that i got hurt by his behavior in farewell party but never ever tried to tell sorry ,he was waiting for me to propose him,he saw the blog and from the next day he stopped coming to the mess ,but visits my profile (orkut) by hiding it and in his profile he kept every thing to my interest.Now he is out of the college it is almost one year that we have never looked at each other,he did not call me on bday atleast,he has every detail of mine(but never mailed or called),i told to my parents that im in love with tat guy they refused bcz we are of diff castes,i feel that he loves me very much bcz in his profile he writes ieverything as though he loves me a lot,recently i have locked everything in my pofile he also did the same,wat does all this mean ,what shld i do now? shld i fight for him with my parents ,does the boy really love me(one interesting thing is he is not in any one my lists like yahoo,gtalk ,orkut and etc., he never ever tried to do on his own,when i do any thing he just acknowledges)
