A close friend broke a very big promise to me, knowing just how upset it would make me. She did so because she has been having a hard time lately and decided that it would be the best thing for her to back out, which I completely understand.

So your friend is not necessarily lying to you when she says she values you. But she hasn't acted like a real friend would, either. Delivering on promises is a...
