Apprently that "communication breakdown" is still pretty much in affect and your ex bf certainly doesn't want to rekindle your relationship. I think if he actually wanted to, he wouldn't need one minute, never mind five days to mull it over.
I don't know why you even dredged all this up again anyway? Long distance relationships rarely last the test of time if there is no set time that the two of you will no longer be long distance. To rekindle when there is no shelf-life in place is just wasting both of your good dating years waiting.
You want to call/contact him so just do it and get it over with instead of becoming sick over this.
Love isn't enough to keep a relationship nutured and working.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
