My ex...

I need some advice to move on… I asked my best friend that was a girl out. We were friends for two years before that.We went on one date… but I said the L word by accident….She dumped me in February..I don’t blame her…We were still friends till June…Then we got into a small fight. I told her I was very sorry.She said it was ok. Then we havent talked since June.Because it was summer time. I have dated other girls, but she doesnt know because it was summer…but I still cant move on…

  Every time I watch t.v I use to think this was her favorite show or when I listen to music or I am on the computer..or when I read...Sometimes at night I feel like my heart just drops for no reason. She is in one of my classes.We arent exactly talking now... And I dont know what to say to her because its been so long...I tried e-mailing her to say hi and no response...
 Is it just by seeing her that reminds me of the pain..and I just cant move on?..I dunno. Its been since February since she dumped me and I am still in pain is that normal?I just dont know what to do.....I still have feelings for her.. please help...
