Yeah...it can be a let down when it is a quiet week and nothing to look forward to. That is the reason why patience is so important but SO difficult when you are in the think of it all!!
What makes you think she is going to hook up with OM soon?

You are better off than me with your baby steps/goals. So far I have only achieved one, which was the H finally expressed emotion/sadness to me...he was just so cold and distant in the very beginning. So, good for you. I would not ignore or discount the importance of this. It is great! You have time to work on your next goal...don't give it up even if you think it is a long shot.
And also, you never know what might happen tomorrow. It is the way it goes. I know you didn't expect her to invite you to the bar that night...
I would give it time before you ask her out. Be a little more mysterious if you can first. She may be more likely to say yes when the time is right. Anyway, sounds like you are just venting here, and by the time you finish your post you are more sure of what to do. That is what this board is for so I would trust your own instincts and you will project your confindence at the same time.
Now...lemme try to follow my own advice!!!!!!
