I feel like my husband and i will never have children together - religion

My Husband is my best friend. I love him, we’re super open with each other. We are learning to work out our disagreements and differences..with that being said, almost 6 months ago he decided to start practicing Islam... he started praying like 5 times a day, learning the language, talking about the beliefs. This isn’t his first encounter with being Muslim but this is the first time I’m seeing him practice the religion. In the past we have prayed together gone to church together and discussed the Bible and we were both raised Christian. I started feeling him pull away from Christianity and lean toward being Muslim. Ok that was hard for me. Idc what any one says, it is hard being married to someone to doesnt believe in living a certain way or doesn’t believe in the same God

..anyway the other day, he told me that he wants to raise our children Muslim.& I’m like No way. And every day I go through all these emotions and thoughts on if this is something we can work on or through or if this is a deal breaker....
