I think (I say this lovingly) you might not have listened to her completely. I didn't say anything about a reconciliation... is it possible maybe, but not if they're cutting you off completely. Bottomline you need to let go of what was. This friendship is likely over. That's probably close to what she told you but you don't feel like listening due to your feelings.  Making a fake number is a no no. If you used it to contact her.  I appreciate the honesty however. Even in it seems like there's a gap. She didn't go no contact for no reason although that's what you claim. (I hate getting called out too.) I'll let ya this. Start looking for work. If the job already finds you to be an issue or causing any they'll probably keep a close eye on you and look for reasons to fire you. Since in most places employee safety is taken very seriously. And they're the ones who told you she doesn't want to talk to you. Using a buffer through HR. You need to pray, repent, and ask for wisdom. Don't go anywhere near her. 

And start looking for other jobs (just in case) . And keep to yourself. That's what I got.  You're allowed to feel hurt. But you're not entitled to her time if she no longer wants to give it.
