I love the list of positives... I see him making an effort to reassure you of his whereabouts. Perhaps you can lovingly discuss with him what goes on with YOU when calls like that occur. He appears open to making you feel more secure. Don't accuse..ask for his help. Make him feel needed and in control. Maybe you could even make it fun...tell him you need to schedule an appointment with him for some "medical marital" advice. Make him the expert on your R. He may be touched and pleased to help.
