Excerpt from my latest Sasstrology article (please leave comments on the Sasstrology site):
"Romantic compatibility is about more than Sun signs. However, there are certain signs who get together and appear to be full-on incompatible. How is it possible for two radically different expressions of ego and purpose (which is what a Sun sign is) to coexist in a relationship? What draws them together in the first place? Most people know that you have to look at the entire charts of both parties, and this article is not suggesting otherwise. But Sun sign compatibility does play a role in how two people will get along in a romantic partnership."
