Significant others

I've been dating my boyfriend for two years. I was already diagnosed when we started dating. Sometimes I feel like he doesn't take my D very seriously. I have tried to teach him about it but he just doesn't get it. He has no idea what to do if I'm low, or if I'm high. Don't get me wrong, he's a great boyfriend, and I'm not sure if I'm being too sensitive (my last boyfriend's sister is T1 so he always knew what to do.) How does everyones significant other handle D?
