Meant to Be

We met but the timing isn't right. I have my reason and he has his. He told me to wait for him and so I did. We met again, but this time He let go.
And walked out of my life again.

They say, If you are really meant to be with him/her someday you'll meet again.
but What if too much time had passed?
Will you still wait for the one you thought that is meant for you?
Or tell yourself that maybe, he/she is just meant to be forgotten?
