"I was hoping that'd be you."
One day there will be a psychological study that proves how this golden little phrase saved 91.9 out of every 100.1 marriages in an experimental group of couples monitored over 53.8 years. Until then, just say it, please—most particularly when he calls. He, too, is aware that, in this age of texting, the sound of a phone ringing (or chirping or playing jazzy glockenspiel) is irksome. By saying this to him, you make him also aware that this minor irritation is, in fact, an experience you look forward to...as long as it's his voice on the other end of the line.
