I was in an unequally yoked relationship and it just ended really bad....I ended up backsliding, even though he was trying to be a christian, but you cannot try to be a christian, you are either born again or not.. At the end of the day it was the lust that kept us together for a while (you see how bad this is). Eventually he broke my heart and thats how it ended. It could never work for several reasons... Unbelievers are mostly lead by their emotions, and they dont really stick to the promises they make, because of being emotionally unstable. And it causes you to get hurt and tossed into being emotional as well. My experience was so heart breaking that Im still even today mending my heart because I got hurt too much. Dating an unbeliever is a very, very, very bad idea ! Believe me, it is !
