Friendships

My best friend and I got in a fight bc I told her she was being a hypocrite for doing drugs behind her sober bfs back (he got sober for her). She lost it on me, I left. She's been sending me nasty texts since. I haven't been mean to her otherwise, even when she's been saying tons of rude shit to me, I just asked her for space. Twice when she sent me rude texts I called her to work it out and she didn't answer. I left her calm vms apologizing and telling her we'd work it out when we were ready. Oh yeah, she's my boss at work and my only friend in the small town I just moved to. 

What should I do? Do I wait for her to come to me? I don't really want her to continue saying mean shit to me, and at this point I don't know if we can even be friends again
