Aries are one of the most stubborn signs in the zodiac. They will not last in a relationship in which they are commanded and told what to do.
Obviously, this does not imply that you should submit to their commands.
They cannot tolerate conflict, therefore if you are lousy at compromising and insist on having your way, it will irritate a Libra.
They will feel awkward communicating candidly with you, which is a negative indicator for the relationship.
They are able to set aside their emotions and examine an issue logically, and they want you to do the same.
They are all about compromise, teamwork, and justice, so they will always hear what you have to say.
Leos are passionate. If they desire something, they will fight tooth and nail to have it, since they never give up.
This sign could wind up giving you orders and instructing you what to do if you're not careful.
