Like Rakesh_ql said, its better for the two of you to actually sit and discuss.
It really depends on him as he will be the one that has the biggest issues to deal with (family, etc.).
Im christian and happily married to an arabic/muslim man. His family was fine with me after a couple of months and now there is great acceptance and love with his family and me. It just depends on how far he will go for you.
My hubby and I support both religions.... he supports easter and xmas with me (although when we go to Xmas eve service, he'll wait in the car.... ha ha ha) and I support Ramadan and his traditions. We enjoy them both together.
Especially as long as there is no pressure to convert, its fine.
If he's the right guy for you, you will both find a way. If not, move on. But, dont let religion stand in the way of something you will want together in this relationship or in a future one.
good luck.
