i am glad you enjoyed your time together... i do see your situation differently than you and Nicole do... i am of the opinion that everything she said to you was predictable... noncommittal... it's easy to latch on to the idea that all the self-improvement would be undone--that's a great reason to be concerned about as far as having a relationship with you goes... she said all the things i would have said if i wanted to let someone down as gently as possible without actually saying it--because i have been gutless in these types of situations... it's like what i have often pointed out to hoosjim... words mean something... they matter... words that are spoken and words that are not spoken...
everything she said to you is why i think you really do need to move on... i believe that your chance at truly getting her back will not happen until you move on... at that point--when you have moved on, and she declares she wants you back--you would have a decision to make... but if you do enjoy hanging out with her, and you are in no hurry to have an exclusive relationship with anybody else, then--enjoy yourself for the time being... you just won't be moving toward to relationship with her--in my opinion...
