There are a lot of things that your zodiac sign might be able to tell you about your personality. From your strengths and weaknesses, to your fears, likes, dislikes, and more, your sign can help explain a bit about who you are. And just as your zodiac sign might tell you about yourself, your partner's zodiac sign might give you some insight about them, as well. If you're wondering how they'll fight or communicate, if they'll cheat on you, and more, knowing about their zodiac sign might help a little. Knowing the zodiac signs that are most likely to stay faithful to their partners obviously doesn't guarantee that your partner will or won't cheat because cheating is a complicated issue, but sometimes knowing what someone might be more or less likely to do can just make you feel like you know what to expect.
"In astrology, the temptation to cheat also depends on additional factors, such as rising sign, fifth and seventh house planets, and aspects between those planets," Ally Mead, of Sassy Psychic, tells Romper in an email exchange. "So it’s always best to get a complete read on a chart, rather than just focusing on the sun sign." So while knowing your partner's sun sign still might not give you the definitive answer you may be looking for, it's still fun to know what their zodiac sign might say.
