Not judging, just observing there’s only so much you can do. But perhaps that will slowly and gently nudge him into being more proactive. Fingers crossed.
Testing right now, if limited needs to encompass before and after a meal. Morning fasting won’t teach you anywhere near as much. So pick what you think is the meal most needing to be addressed test immediately before eating and again 2 hrs later. If it’s gone up by more than 2mmol it’s too much and the meal needs changing. There are nuances to this but this is the starting point. Ideally the closer to matching the before figure the better it was. This might prove eye opening to your hubby. It is said anything g about 7.8 can contribute to the slow long term damage. That might be a way off being achieved in the short term but it is a goal to aim for.
Also if testing is an issue make sure you are doing it in the most pain free way possible. Warm, clean, dry finger. Before pricking massage from palm to tip a few times. Use the lowest setting on your device to get the necessary amount of blood. Prick the edges of the fingertip, not the very top or mid pad. Some fingers are better than others at bleeding. Let it rest a moment after pricking and if no blood a gentle squeeze from the base of the finger upwards. Rotate sites allowing them to heal between rather than stick to one favourite.
