Most Helpful Guy
probably he's was't sure about what he said. so you should expect less results (less attention).

He probably didn't mean what he said. If he did , he would act on it. The only reasonable explanation (s) for this is
A- He wanted to see if those same feelings would be reciprocated back. (This makes him feel good knowing you haven't moved on and are still available)--He feels he has that much of an impact or power over you because you still haven't let go.
B - He got cold feet.
He wanted to work things out but he changed his mind. He figured it's best that you both don't keep contact. Regardless , he still could have went about things in a respectful way (instead of cold).
I know this hurts.
But I think the best thing to do is, look forward and not back.
