It's fantastic that your husband shows an interest in your recovery and takes you to meetings. However, if you want to go to more meetings and getting there is a stumbling block as he can't / won't take you, it's always worth mentioning at your local meetings as someone is likely to be going to other ones nearby and offer you a ride. Especially when you're shy and don't like speaking in groups, when you get lifts to meetings it's a great opportunity to chat in a more comfortable 1:1 way. That's how I got to know a few people really well who have become good personal friends.
