Does anyone else out there live with a spouse who has diabetes type 1, and have to deal with their mood swings?

My husband has diabetes type 1 and when his blood sugar is too low or way too high he gets angry even at stupid little things. He ends up complaining alot and blamming me for things I didn't do. Later he acts like I started it all in the first place. Sometimes he says he's sorry. How do you cope with mood swings when you are the spouse?
