FWIW, I don't think unconditional love is possible between people. It could be argued that sometimes parents might have it, but I don't think that's a good description of romantic love. "Agape" love, aka unconditional, is what God is said to have for all of us. I'm sure there are plenty things ("conditions") your fiance could do that would make you leave him, which means that it's not unconditional. At least I hope you have certain standards that if broken would make you leave him...if not, raise your standards.

The type of love you're looking for is romantic love, but really you're just describing a certain kind of faithfulness...you're expecting him to be faithful, which is important, but it's by no means the same as unconditional love. Love is not the end all and be all of a relationship, as people here are pointing out to you. You need to trust him, and you don't. You're very insecure if you're threatened by your fiance walking his classmate to her car at night. If I were Dr. Drew, I'd ask you what the real issue is..."Were your parents divorced?" or "Were you abused by someone close to you as a child?"
