Well it definitly sounds as though she is moving on, but this doesn't always mean the end! It could be that she wants something new, right now, but in the long run we always go back to what's familiar, what's comfortable (which is you).
I don't want to give you false hope, maybe this is the end of that relationship, and the beginning of a new one, if you allow it to happen. Don't rush into anything, like I said before meet new people, play the field, maybe she wasn't the right one for you, maybe she is still out there waiting for you!!
If it's meant to be, it will be!! But, it will happen on its own!!!!
Have you by any chance seen the movie "The Break-Up"? Watch it and you will see by what I mean, that if it's meant to be it will be!!!!
