Guys have made kind of a joke out of the "Dreaded Friend Zone," supposedly labeling it as a pit of non-romantic feelings that you'll never be able to crawl out of...
a point where all you'll ever be to the one you care about is "just a friend...
"  But is that really it, or can more come of this situation? The truth is, you can indeed get her back after this point has been reached.
  Actually, if it's the right kind of "let's just be friends," you couldn't really hope for a better place to be as far as getting her back goes.
  I know, obviously you're hurting and desperately hoping there's a way to fill this hole in your heart, but if this is your situation the outlook is actually very positive.
The reason she's holding at arm's length is because she's having a hard time understanding how she feels.
  You can identify with that, I'm sure...
all the emotion and drama of a hard breakup can wreak havoc on a person, and surely you can remember a time when you weren't sure how you felt about her.
  It's only natural for her to question her own feelings, and being in her life by her choosing is a good place to be right now if you want to get her back.
The only trick is helping her to come to terms with her emotions and figure out how she really feels about you.
  This can be a little slippery work, as the human mind can be a little fickle and doesn't always listen to what the heart is saying...
but with a little skill and some help figuring out what to do, you have a great shot at reconciling and starting a new age with her.
