I have a really really close friend that all of a sudden stopped calling & returning my calls for almost a month now. We used to talk everyday. I emailed her & all she says is she is really busy. I'm so confused. I know I didn't do anything to her or to make her mad. This really hurts. I'm a adult & thought that adult friendships just don't end like this or at least without a explanation. Has anyone ever went through this & how did you handle it? I think about it everyday & I'm having a hard time letting it go.
