Hi, I am a Rat male born in 1972 and my gf in 1981 a Rooster. Are we compatible?

To be frank, it may be a little reluctant for you to stay together 'cause it is not really a good pair from the aspect of Chinese astrolgy. In spite of this, you will achieve happiness as long as you have great affections to each other. Mutual communication in daily life will make you more intimate.
