Best Friend or Frenemy?

Over the past year, my best friend and I have been drifting further and further apart. We have always been inseparable. I admit, that she has always been the more dominant one in the friendship.

I am more easy going and flexible while I consider her to be more controlling. With her, it is usually "My way or the highway". Whenever I wanted to do something different or new, she would not give in and is content with her routine.

Also I am the more attractive friend, and I think it bothers her. She would often make snide little comments and repeat things that other people have said about me. This makes me think that she is jealous and insecure. And despite that, we have gone through many hard times together and honestly care about each other (at least I do).

When my mother was ill she was completely there for me. Lately however, things have gotten worse. I have recently moved in with my boyfriend and things are going well. Instead of being happy for me, I feel like she is shutting me out.

We hung out a few weeks ago and thought we cleared some things up. She admitted that she was upset that I hadn't called her as much and said she was hurt. I thought it went well. However, lately whenever I contact her she gives curt replies.

All our mutual friends don't understand the problem. And I honestly don't as well. It makes me think that she is resentful of my relationship and of me. What makes things even more complicated is the fact that we live in the same building and our mutual friends come over to both our places. I don't want to create any drama since we are neighbors. Is this friendship worth saving or is she really just a toxic friend?
