<human>: I have already done search on past posts but most of them are from shorter relationships/younger people and not very similar to my situation. 

So we've been together for 2 years, living together for last one. We moved pretty quick initially with her moving cities and spending almost every night together. In the past two months we've both expressed that we are more distant and haven't been giving the relationship the effort it needs and treating it more as a constant in our busy lives. 

Last week she initially told me this not being in love with me thing and we ended up having a good conversation. I understood that it happens in relationships, eb and flow and whatnot. We also agreed to work on it, knowing it's gonna take work and time but still hopeful. She said she still want us and wanted it back. Flash forward thru an awesome weekend with friends and vday, everything seems to be going swimmingly. Then I notice she's feeling distant again and we talk again. This time she's not sure and just confused. She says she doesn't know who she is as a single person anymore (to which I agree that's scary and if you can be an individual in a relationship then you shouldn't be in one. At the same time there comes a point where you don't know the single person you would be. Semantics between individual and single). So she needs some space to "grow" and figure some things out. Hard to do when you live together but moving out feels more and more likes bullet to the head for the relationship. 

Anyone ever have this and manage to come back from the brink or is it time to move on?

Can you give me the gist of the text in a nutshell?
<bot>: girlfriend of two years blindsided me with needing space and not being in love anymore. Still loves me and not sure if she wants to give up on the relationship or not.
