I don't think you messed up, completely. I think you have a right to stick up for yourself and your needs (part of not being a doormat). But now that you've put it out there, the ball is in his court. You can't control when he will respond, even though you want answers now. Try to go dark, now. You've said your piece, (if he can read) then he knows how you feel and what you are looking for from him.
Here's the really hard part: don't bring it up again, in email or text. It's going to drive you crazy waiting and wondering what he's going to do. (kinda like all of us waiting for our WAS to come back/ make up their minds) The 'not knowing' about future events is really tough.
What is something that you like to do, that distracts your mind? For me, it's going to a movie (no love stories though). Some people go for a run and blast the music to drown out their thoughts (I can't run b/c of my heart, but sometimes I wish I could) Give yourself a goal of doing something like that this weekend, at least once.
Then, you can come back here and tell us all your scared/pathetic/sad/anxious thoughts from your day.... we can hear all that, he can't.
