If you are in a relationship with an Aries, you have to be innovative, because they can easily get bored. They don't want to listen to stories that they have already heard, so you'll always have to bring up some fresh topic to talk about. It would be perfect if you had many friends and a lot of different things you're interested in.
Taureans are passionate. They are loyal, and they will expect the same in return. Support their dreams and plans, and let them know that you'll always stand by their side. Lavish them with your attention and be a good listener.
They perceive themselves as exceptional heroes, so you should always tell them how brave they are and they will soon start to believe that you are soul mates. They have a strong need to be independent when in a relationship, so let them have their freedom and make them feel that you are a true friend.
Cancers don't like too attractive girls; if you pretend to be a sweetheart he will definitely fall for you. They like to do those minor domestic works, so you can give them a set of tools or something alike. They will appreciate the gift, especially if it without any particular reason.
Leo remains in love with the girl who sincerely supports him unconditionally, and loves him the way he is. You have to know what is important to him at all times (playing guitar, automobiles...) and show him how you admire it. Leos are generous, so if you let him take care of you, and you compliment him for that, he will be very happy, and you will be satisfied with the relationship.
He will stay with you if you convince him that, in fact, he needs you. Ask him for advice and always let him know that his advice are very helpful in solving your problems. That will make him think that you need him, but in fact, he will need you.
You'll have to be his true partner, if you want to keep him. Be his best friend, support him and try to enjoy his stories. Share your thoughts with him. Believe in him and he will be yours forever.
They need more time than anyone else to open up to someone and fall in love. But when they do, they are completely loyal. Do not lie to him and make him feel safe and loved.
They need a lot of independency in the relationship. If you let him have his freedom, without being jealous, and you are ready for fun and entertainment, you will have a true partner for the rest of your life.
Be honest and reliable. What he confides in you, you should not tell others. He will expect constant support and encouragement.
You have to give him some space of his own. Be intimate with him, but do not bother him with telling all the time how much you love him. If you want to get love, you'll have to give it as well.
He is very sensitive, so avoid criticizing him. Even if your opinion is completely different than his, show him that in a gentler way. They are deeply romantic, so you should weave threads of romance into your relationship.
