I'm am American Wiccan woman and am involved with an Arabic Muslim man from Tunisia and would like to know what are the religious beliefs about us getting married. I am not agonistic or atheist, but am concerned that this could be a problem. Could you please help me with this?

Depends on if he takes his beliefs seriously or not. It he is a real Muslim... most likely there are going to be very big problems with you two getting married. Just as in Christianity, Islam teaches a single, personal deity that does not permit a relationship outside of that faith.

How long have you been involved with each other and how much have you discussed this issue? That's at the heart of the matter because despite the labels, we all observe or practice religions differently.

Forget a marriage until you know what he would expect of you, and you him.

Being a muslim it is almost impossible for him to accept your line of thought. Because islam don't allow deities. But there are liberal people. You need to discuss lot of things before getting married, your faith as well as many other things.
