The JustAnswer system is full of glitches these days. I have 3 in a row of your same post, so perhaps DearDebra didn't get anything, or something else happened. Here's my 2 cents worth: You're freaking out with embarrassment/awkward/doof!--aka feelin-foolish, because your heart's out on your sleeve and you don't know why she hasn't at least wiped her nose on it.
I've skimmed your conversation with DD, and I'm an expert on relationship histories. She's protecting herself when she says she's going to be single for a while. And she's strongly drawn to have her "healing relationship" with you. But if she does that as MORE than "friends" this soo, then she can only do it by semiconsciously being sure that you're more into her than she is into you (which you are, right now), so she won't get hurt if you turn out to be (somewhat) like all the rest of the guys--but then she'd also feel guilty for using your greater affection for her safety when she's just not ready to feel too much self-surrendering-love until she's felt more of the mourning and cleaning-up-afterwards feelings about her ex.
So step back for a minute and think about YOUR last long-lasting relationship. How long ago did it end? How much were you in love yourself? What did you learn from it? Perhaps you can email her about how you are pausing yourself to see if there's more you can learn from your own past, because you understand that she needs time to think about what happened and learn from that, and to feel her losses. You'd be inviting her to share her relationship lessons with you, which might help her get through her mourning process. And if you did some serious reflecting on your own past relationships, you might be less head-over-heels and more clear-sighted about yourself and her (cuz self-reflection about our own pluses and minuses in loving is something very few guys do). What you're seeing in her you might be doing yourself also: namely rushing into it, because it feels so great to be "in like" again, but then freaked out because you haven't attended to and treated your own bruises and they're throbbing like mad the moment something might be snarled up.
So maybe you actually know pretty close to exactly how she's feeling, Because You're Doing the Same Thing and feeling the same things: such as "This could be too good to be true!"
So if you really want to ring her bells, you could write her a little poem (whether in free verse or just regular prose) about the guy or girl who got to first base on a bunt and then stole second! But s/he's wondering "how many more chances can I take?" cuz that's a little like where you are in this inning.
You've got many more innings to go, since you've had years in the dugout already. But now, just hang tight in the on deck circle and keep winking at the pitcher. (That means: ENJOY YOUR ANTICIPATION and don't worry about blowing your chances, time is on your side.)
