Aries won't stand for this in relationships...
If you're shy and retiring, you don't have to worry about tiptoeing around Aries, because you probably won't be going out with one in the first place! Rams like the thrill of a challenge, so the timid need not apply.
However, if you're determined and intense, you may meet your match, because that's just the kind of person that attracts the Ram. Even if you're a tad restrained, the right Aries might just stoke the fire within you! Make sure if that happens that you let them see that spark.
But if you try to dictate terms, give orders, or tell Aries what to do, you could be shown the door. Have a better idea? Find a way to make it seem like it was all theirs (and then praise them to the skies)!
