Can't resist: but dammit, why can't she give us another go!
I can give you one very simple, major reason she is definitely no closer (maybe even farther away now?) to doing so: it is because YOU HAVEN'T GIVEN HER THE SPACE SHE NEEDS, BRO. You can't just go a week or two or three without R talk, flirting, etc, and then do it, back off again for a few weeks, do it again, etc. You need to DETACH from her completely and for as many MONTHS as is necessary (and who knows what that is). You know too much about DBing to keep doing this stuff to yourself, man. I honestly just sit here and shake my head at this point when I see your backslides. It doesn't do any good really to give you DB advice, because you've heard it all before and know it by heart by now, I'm sure. I'm just going to start saying, "naughty boy, Heim -- DB next time, okay?"
Also, I'm with OT on buying your slip of "Love You" via email. How long has it been since the bomb was dropped (7 months, maybe)? This separation is not a new thing, so we're WAY past slipping on Love You, my friend -- esp because you did it via email, and thus could easily see it and erase it. You were not in a form of communication that was word vomiting in any sense -- you had ample time for reflection of what you were typing. I hate say it, Heim, but I'm calling you on that defense. HOW COULD YOU NOT SEE IT?!
