There is another possibility that biiv didn't mention. The good point of writing something down is that it is there to go back over & over.....maybe she might not be ready for anything right now, but with the words being writen down rather than spoken, they exist as you say them on into the future when she might be ready to respond.

There isn't anything wrong in reaching out without applying any pressure.....just letting her know that you are there & will be there when ever she is ready (if ever) to continue the friendship.

Go for it...you have nothing to loose,
