<human>: Can you give me the gist of the text in a nutshell?

I've known this girl for a few years since taking some university classes together, and often riding the bus together.  I've only ever considered her as a friend.  Recently she started dropping increasingly-obvious hints that she was interested in me romantically.  

Last week I told her I thought of her only as a friend. She seemed understanding, and said that she had to take the chance, in case there was a possibility of things working out between us.  She said she wanted to still be friends, though I could tell she was upset.  I haven't seen or heard from her since then.

Here's my question: should I give her space to heal, or try to talk to her?  I meant it when I said I still want to be friends, but since that seems to be a cliché way of telling someone you're not interested in them, maybe she thought I was brushing her off.  I was thinking of sending her a text saying that if/when she's ready, I would happy to still be friends, but I'm not sure if that would just make her feel worse.
<bot>: I told my friend I want to just be friends, and I meant it, but I don't know if/what I should do now.
