Have you ever been ditched by your best friend?

We were friends for 8 years. She was like a sister to me but then she started working at a new place and I got replaced, she started texting less and we didnt hang out as often. The breaking point was when we were having lunch and she kept texting and not into the conversation that much. I was pretty hurt and told her, she said she had changed and it embarassed her and couldnt look at me in the face. We didnt talk for months after that. I feel like she's trying to reconnect and I might sound like an asshole but I dont feel like it. I also have new friends now and they're more supporting.
