Can someone give examples of relationships working out against horoscopes?
What everyone else said–plus some other stuff. Romantic relationships you have to at least look at Moon, Venus, and Mars as well–governing your emotional life, attraction and romance, and sex respectively. Plus you want to look at the sign that governs your 7th House, which can often indicate compatibility in marriage or a long-term partnership. Even if that all works out, I can give you plenty of examples of things not working out even with favorable synastry. Why? Because people are basically selfish, rotten, and untrustworthy. You’re lucky to find someone who is decent, whatever their chart says. Astrology is a guide to personality and personal challenges. People still make choices about who they ARE.
