Practice phone etiquette. If you must look at your phone, announce that you are doing so. “I am just checking the score/weather/playlist for two minutes,” shows courtesy and indicates to your partner that you are aware that your attention is shifting. It may also make you more aware of how often you pick up your phone when your partner is present.
If your partner’s job demands round-the-clock availability, discuss reasonable boundaries that would satisfy both the job and you.
