Hi, i am Taurus and my fiancee is Aquarius. How compatible are we in the beginning, middle and end?

Well, your compatibility rating is 50 percent. Even you are attracted to each other, you both still feel that there is a gap between you and her. You don't know how to close your gap. Aquarius needs someone who is always patient. And he must be able to appreciate her uniqueness. If you are the one who meets the requirements, you two will have a chance to be together.

i am 10/05/1987 Taurus, she's 11/02/1994 we both married but always fight. what can be done to resolve this?

There is no large problem about your love compatibility. However, maybe both of you need to be more patient and try to stay calm when facing disagreements. After that, have a deep communication and better understanding of each other. Best wishes!
