I think that you've made a wise move in backing off gently. Reassuring her that you'll always be there, if she ever wants or needs to talk.
I've been in the position that your gf has been in a few times, but I never had the strength to push my hub (and then bf) away. I was confused too! Seriously confused as to what I really wanted in life, who I am, what I want, etc. A big consequence of me resisting letting go of them was making the pain and confusion last longer. My bf has offered a few times to back off, if that's what I need. To let me find the answers and the hope that I need. I'm still too scared to take him up on the offer.

Maybe someday.
So, I'd advise you to be there for your ex-gf emotionally when she does come to you. But, be careful. Don't bring up your emotions or sexual desires until she's gained a lot of strength and independence. She really needs to know who she is, and how she honestly feels, before moving on to a deep commitment. Trust me on this one ~ I've got too much experience in this department! You will both be much happier if you back off and allow your gf to simply live without pressure to fulfill your desires.
I wish you both the very best!
