I guess those abuse rumors may have some merit to them.
If that’s the case, then yes, I agree it’s a very inappropriate phone call. However, I think there’s more to the story than that. I’m imagining they got in a heated discussion/argument which embarrassed him to have to deal with - and then she may have hung up on him, when he called back and left that message. That’s the only way I can imagine him leaving that kind of message - unless he really is looney.
