How to love an Aquarius

Be open to their advice, let them talk about their interests, be down for spontaneous adventures as well as cozy nights at home. 

Have a debate with them, become well versed in the things they are passionate about, and take up a hobby together. 

Always respect their space, let them have some independence. 

Make them feel loved no matter what even on their worst days.

Be "almost" healthily obsessed with them. 

They may disappear on you for a few days but it's alright, they're just keeping their guard up. They'll come around. Give them their space. 

They're afraid of wearing their emotions on their sleeves. Don't be afraid to get an ice pick and try to chip away at it, slowly but surely.

Don't ever lead them on. 

They're never meant to be rebounds.

If you have unsettled skeletons from your past, don't ever expect an Aquarius to forget about it then fix your problems for you. Deal with that first yourself, then pursue. If you refuse to do so, then shut the door.
Make them laugh so hard they fart or cry or both. 

Be their cheerleader, no matter how big or small the victory.

Don't be afraid to be spontaneous.

If you're not ready, they're not ready for you either. 

They tend to be shy, they tend to be closed off, they tend to pick fights with you. But it's only to test and see if you're actually tough enough to withstand all of that, put up with them, and then some. If you can't do it, then walk away sooner rather than later. 

Be their best friend above all else.
