why tiger and snake can't be together? i really love this guy he is snake and i am a tiger.

According to Chinese astrology, this may not be a good pair. Conflicts are easily to be raised and both of you are impulisive. You cannot believed each other. Even the marriage life cannot make you to establish a trustful life. Lack of common interests, it is hard for you to communicate, too.
However, in my opinion, if you love each other and can solve these problems, you can live a happy life.
