What does it mean when it says that Aqua is unemotional?

They don't give up easily. They detached themselves when they worry about something bad that might happen - don't bug them when they get like this or they'll only run further. Most Aquarius people I know are very romantic, and they DO have emotion, they just chose not to show it or talk about it. This is when they get detached.

I am not an Aqua but I've been with one before...

and well, they claim not to be and don't show it but I think they are a lot. It's almost like the more they try and cover it up, the more it shows.. lol.

I don't think it's that they give up easily.

IMO, by unemotional(or detached) it means that they don't express emotion easily. Or they may have trouble dealing with strong emotions(theirs or someone else).

I think it makes them somewhat uncomfortable or they may get overwhelmed.

They definitely HAVE emotions(everyone does, afterall) They just go about dealing with theirs differently. Mainly by taking some time off to themseleves until things settle.

From my experience and people who are Aquarius in my life, they would just rather not deal with heavy emotions. Like my father(he has an Aquarius Moon) gets upset if you ask him if he's alright. Catch him crying ONCE and he'll retreat into his cave for a year, ha ha.

This air sign is light as air, if a convo gets deep(like a water sign) then, things are NOT light. They are heavy and gushing with emotion.

I know an Aquarius with a Scorpio Rising and Taurus Moon and they are EXTREMELY sensitive. They just bottle it all up. The Scorpio Rising just makes them even more private about their inner feelings.

Aquarius people think with logic not emotions. They sometimes keep their emotions hidden. Aquarius people do not let their emotions rule them. They hate arguing with people and just let it ride......They can be emotionally detached but not as much as other signs.
