My first suggestion is that you stop looking at the cell phone bill...seriously...you will drive yourself crazy with it, trying to figure out the whens and wherefores (and whys!) of the phone calls. It's just going to increase your anxiety level.
My second piece of advice is something you already suggested to yourself. "drop it", take some deep breaths. Here's something I use to retrain my mind when the going gets tough "it's HIS drama. I'm not going to participate in it".

Relax. Appreciate. Be calm. Laugh. Enjoy. Be secure. Be loving. Be loved. Don't personalize. Don't ASSume. Accept. Be grateful.
