It might be a little more difficult than it is with other men, since it’s harder to tell when an Aquarian’s behavior has become stranger than usual! But, speaking generally, being in love is such a powerful experience that there is no real difference for an Aquarian than for anyone else (disclaimer: I am an Aquarian myself). The way the Aquarian expresses his emotions will be signified more by his Moon sign, and his attitude and approach to relationships will be signified more by his Venus sign.
But if you’re interested in an Aquarian man, and are wondering how interested he might be in you, there are a couple of thoughts I’d like to share. One is that Aquarius is the most impersonal of the signs, so he might seem relatively cool and distant even if he has strongly positive feelings about you. And while an Aquarian can be as strongly attracted by beauty in a woman as other men, maybe even more so, since Aquarius is a beauty-oriented sign, with Aquarius there must also be a mental connection; without this, there won’t be any lasting relationship. He has to like your mind and feel simpatico with it. If he does, then your chances with him are very good.
A common problem with Aquarian men is being stuck in the “friends” place. You go out with him a few times and wonder, “So does he like me or not?” The issue here is that, while for most people being “just friends” is a dead end and the kiss of death, to an Aquarian, it’s something good! Aquarians value friendship highly, and commonly regard it as the best kind of relationship. So he’s quite happy to stay parked there and doesn’t see it as a negative in any way. But feel free to raise the issue with him; very likely he’ll be happy to talk about it and talk through it. Once he understands that you’re wondering about whether your relationship can be deeper or more committed, he might very well say, “Gee, I hadn’t thought about that—but it sounds great!” It might take some nudging to move him on to the next stage, but he can be moved on.
If you do get mixed up with an Aquarian man, know that your relationship will not be conventional. He’s a different drummer, and does not think or behave the way other men do. He’s going to surprise you and maybe shock you from time to time. You may never get a rose from him on Valentines Day, but it’s possible that one day, while standing in a supermarket checkout line with you, he might look at you and say, out of the blue, “Do you know how beautiful your eyes are?”
Or something else as unexpected.
