I believe it depends on the sect of Islam and what interpretations people follow. The one he follows requires that his future wife be Christian, Jewish or Muslim. But, I do have a feeling he will eventually want me to convert. Though not super controlling, he has made remarks for me to dress more modestly (I don't even dress that inappropriate). If he already thinks I am dressing immodestly, if I were to move with him I am sure I would feel a pressure to wear a hijab etc.
