I'm not sure I can be of much help as I'm floundering as much as you are - you can see our similarities here Help - lost all hope
I also worry about how many times can you "start to connect" and then totally "disconnect" without it becoming the final - last - time?
My plan was to become friends trying to stop the "on again, off again" interactions. I'm not sure that was such a wise decision but it seems to be working better than the other so I will wait it out and see what the results are.
I know how hard the wating to see if what you have done is "forever" or if they are just in "one of their moods". I have kept myself busy all weekend (as I knew he was working and that means no connection) but no matter how busy I am it's always in the back of my mind.
