credit scores - what's yours??

I am trying to get out of debt and keep my score high (Good to Excellent) but my husband who has relied on deployment checks to pay everything off, doesn't get finances or why he should keep a decent score. Right after we were married he signed up for a card with a 24k limit (bc now it's OUR joined income) and he didn't know it's attached to my credit now as well. He maxed it out in 3 months. Only way I knew is bc I checked my score. 😡 He's still not taking it seriously and he's killing both our scores now. It gives me so much anxiety bc I've done so well on my debt but he's frivolous and throws money away like nobodies business. 
My score now has dropped another 12 points just last week bc he's not paying enough downon the maxed out card. It's still Good, but barely at 703. What's yours? Am I being irrational and too anxious/hormonal?
