A question for Christians (primarily) but others too?

I was never interested in boys in school (and likewise) and didn't have my first boyfriend and kiss still 21. Because of this I guess I concentrated completely on school. I always thought I would wait till marriage too. I wasn't raised Christian, I came into the religion and this was a decision made by me even before I became a Christian. So I dated my boyfriend for 2 years until the abstinence thing got too much for him. We didn't see each other for almost a year and now we're getting closer again and I just know he's the one for me. I am so so in love with him and I don't see myself spending the rest of my life with anyone else. We're not kids anymore and sometimes I really feel like giving in. He hasn't proposed, and even if he had for the next 3 years we'll be living in separate countries. Is it so wrong for us to have ?
