It's way past my bedtime, but I wanted to say that I don't think you should worry- you've just implemented a pretty big 180. As MWD says, give it time to work- H might need some time to process what you've said before he responds.....
I think the e-mail isn't bad at all. I like it- it's very complimentary to him, states your feelings simply and without pressure and also is a bit flirty and jokey. Perfect.
Now just wait and see. It might take a while but I'm sure he'll be processing and thinking!!
More tomorrow. I have to go to bed or I won't be able to get to work on time tomorrow!!
