I'm a Pisces guy and I wouldn't say I'm controlling - more like laid back, pretty chilled about life.. although I like to take work seriously, and if I'm in a relationship I take that even more serious..
I had an Aquarius girlfriend once, who was the most flirtatious girl I've ever met, it was as if she went out of her way to try make me jealous.. but before all that even started she said to me that she wanted a serious relationship, yet at the same time she couldn't commit to the relationship - always wanted to go out partying like every Friday and some Saturday nights.. and I just couldn't take it anymore, and so I said to the one day "is this you idea of being committed to a relationship?" .. and then she had the cheek to say that I'm being controlling by saying that.... so that's the last Aquarius girl I'm going for...
Like her, I also have a life, I'm into cycling (both mountain biking and road cycling), I go to the beach with my friends on the odd Saturday, or I go play pool with them at the local bar.. I'm 32 btw, so I'm not so much an old man just yet...... but when it comes to relationships I give it my all .. I'm honest and faithful and all I'm asking from a girl is the same thing..... so no, I'm not one of those controlling Pisces.
You talk about manipulation.... everybody manipulates at some stage of their lives, manipulation seems to be built into a whole lot of people, and most of the time we manipulate without even knowing we're doing it, it's as if it's we do is subconsciously sometimes..... I've known a few Taurus to be very controlling and manipulative..... yet they have their good points, they're good friends to have, I know I have few Taurus friends.
