I lost my best friend

I lost my best friend. Her name was grace. I lost her because I got a bf and then I stopped paying attention to her. I blamed myself for it. Then I was able to eventually move on and get better. Then grace suddenly messaged me. And I thought we were gonna be friends again cause that’s what we both agreed on. We had planned a hangout and everything. Then suddenly she blocked me. She gave me a false hope. She made me believe I got my best friend back but I didn’t. I just feel played and it hurts.
