Feeling lost. Advice needed

I got broken up with around a month and a half ago after being lovebombed and discarded. I wanted to take some space but she wanted to be friends and so I tried. Then she moved on with someone else and last week went to meet him (within a month of everything happening). Now she is back from that trip and she tells me that her new guy told her to reduce contact with me(which was already lesser than what it ever was since we were trying to process everything) and that just broke me again. All this time she said that I was her best friend, cried when i wanted to take some space, told me she would fight to keep me as a friend and that she can't see a day without me. Now all of a sudden even that friendship she tied me with, the apparent thing that "we would always be" is nothing. Just makes me wonder what did she ever say to me that was true. I just feel so lost and I don't know which way is up. I don't know where to go from here
