Wow, everyone has really given you some good advice. I know I'm late but as a theist I think it may be difficult to have a serious relationship because that person may expect your views to change one day, so it could lead to some hard times later. My husband wasnt a believer when we married and I found it very hard to maintain the relationship, but it wasn't impossible, so you two should talk about it sometime and get a feel for what religion means to each of you.
"And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him." Hebrews 11:6
