piakichu, it is never easy, almost impossible to forget someone
you love/like so much. The memory will stay, but
somehow u need to seek an effective way of letting
go. If you are stuck in this then it is difficult
to move on.
Or are you not ready to let go yet?
I understand it is very painful to let go, I have been there
before. Sometimes by remembering what the person
is, what he/she had done tears just simply roll down.
Sometimes some people just cry themselves to sleep. I
am one of them.
Good luck.
