The Aquarius is a mental sign, an air sign. So you must first appeal to the Aquarian on an intellectual basis. It doesn't mean you have to be a professor or anything. But Aquarius judges people immediately by how they speak, what they say, their opinions, whether they can carry on a decent conversation. Immediately the Aquarius is attracted to your mind. So if you have a nice, bright, sharp, interesting mind, then you have the Aquarius halfway home.
Aquarians are also in a way characters. They don't mind being unusual and different. They don't want to be run-of-the-mill. So anything in you that is not ordinary will appeal to them. Aquarians are bright, fun. They enjoy exploration in the world at large and therefore will enjoy exploring who you are and what you think.
Let's say if you're talking about an issue. As the relationship progresses, you might find that the Aquarius tends to feel a little aloof. It's hard to put your finger on this. Aquarians are very humanistic. They love humanity. They love people. They love the idea of life, but they love it on a broader sense. They have a harder time with one on one, a harder time forming a deep bond with one person. Because in a way, they're more bonded to the world at large.
So you need to exercise patience and be true and loyal. Certainly an Aquarian cannot be lied to, will have nothing to do with you if you're dishonest. Kind of bide your time. Be patienct. Be interesting, and the Aquarius will come to love the spirit in you.
