He is attracted to Gemini, Aries, Libra.
Aquarius will always need to be independent and, above all, that his partner respects him. They can't stand people who are too clingy or, in the end, end up depending on them for anything. He loves people who have achieved things in life by their own merits, few or many. You didn't come here to have to be anyone's mom or dad. Sorry but no. In the end, it lasts very, very little with dependent people. Aquarius wants them to walk beside him and, above all, not to have to pull anyone all the time. He also wants them to pull them when he needs them, although the truth is that he needs them little.
Gemini combines well with Aquarius because Gemini does everything by itself apart from sharing an element. It sets a goal and goes for it and does not need anyone to stay on its feet. Gemini will give Aquarius a lot of energy, but he will have to control it because he may often inadvertently absorb his own, which shakes Aquarius.
Aries and Libra will also attract Aquarius, especially at the beginning. The point is that it does not always go well afterward because as Gemini, they absorb too much.
