I wish she understood her behavior and how it is affecting your relationship. I can relate to how frustrating this is when someone does not listen or pay attention to what you are trying to tell them. I had a friend who did similar things and it got to the point that at night, I honestly had to turn the ringer off and let it go to voicemail/machine. When she asked why I did not answer, I explained that I HAVE to get some rest that she could call me during the day and I would call her but earlier in the day. She finally got the message that I could have the phone on again, took a week or so, and it was a week of rest and solitude I desperately needed. I could function again. I did make a point to call but on better terms, so also I was not blowing her off but did not have to talk constantly. It made for better boundaries in the relationship.
