Where else does this show up in your relationship? I mean his rigidness vs. your willingness to explore and experience new things? Has this been an issue before? Just going from your post, I find that to be the biggest challenge here, not religion.
Two people in a marriage are going to go through life changes, and not always together, and not always in the same direction. You are very young. Does he expect your beliefs, views, choices, to stay the same? What about his?
Religion may be a touchy subject, but so is money, sex, children, in-laws, career, etc. The two of you need to find a way to get to the bottom of his strong reaction to this? Is it about fear of change, fear of Islam itself, fear of the unknown?
I would advise you to wait to actively explore this religion further until you and your husband can find a way to discuss this. If you cannot, then you have a different choice to make.
My son, his wife, and their three kids are Muslims. I am an atheist. There were some challenging times during the time he was converting, and trying to be a strict Muslim. Since then, he has explored the religion and its practices and found a more moderate way of life. His wife was raised in the religion and so has a broader, and more moderate, view of the practices.
Muslims are allowed to marry and be married to Christians (or Jews). All three religions pray to the same God. Muslims are allowed to pick and choose the practices that fit into their lives (as people of all religions do). So the food, praying, dress, and other aspects you will see practiced to various degrees. My son's family does not eat Halal (too difficult and expensive), prays when they can (challenging with small children!), attends Mosque regularly, and dresses moderately (she does not veil).
