So you’re thinking about dating someone with the same zodiac sign as yours. Or maybe you’ve already fallen in love with your twin zodiac sign? While we can tell you that this can be a good thing because it means that they will understand you, we will also warn you that this can backfire the longer you know each other. Because ultimately, and according to Simone Butler at Tarot.com the other person will “mirror both your best and worst traits back to you.”
