Is it love?

What is LOVE? That you don't care whether that person is perfect and you still love that person? Is that it? Then what about LIKE? I don't know if I LIKE or LOVE him...its really complicated..everybody told me that he has already like another girl..I know..but..why?why can't i just forget him?Just..accept the fact that he is unavaible?I accepted that long ago..but why?why can't i stop thinking bout him?I thought maybe going to different schools i will forget him.. forget that he ever hurt me so badly before..forget every single detail bout him..but everytime when we text each other,i miss him like hell..that day he told me he is going to taiwan,my heart broke into pieces..then when i watched the news at night there was this accident in taiwan..a lot of people died..i think my heart stop for 1 sec..then i tried to call him...but failed..That day he came back,i text him..luckily he replied..a lot of days later..i couldn't take it any longer..so i ask him if he still like me..until today..he still hasn't replied..i guess i know the answer deep down in my heart..but i just won't face the fact...guess it really is time to let go..just like wai yee said..loving someone who doesn't love you is not worth..i never believe that..but now i do..but i just wanna say..he gave me the best time of my life last year...though we were never together..i will always cherish the memories..gosh,i miss him so much!T.T...
