I am a tiger and my wife is a dragon what is our future

The Dragon and the tiger will always fight for dominance, that's why there is a need for clear status in who is allowed to lead. If you were a weaker sign, like a sheep, you could worry, for if the sheep and tiger find themselves in times of distress, the tiger would tear the sheep apart. But your a dragon, a worthy opponent, and you should withstand hard times together given there is shared respect.

I've been reading a book well researched in Chinese history, folklore, and zodiac legends, I find my source to be very reliable.

You will live a happy life dont get it twisted also your married. you got it dude :)
