The past and the present.

I have been very lucky to find an amazing Chinese man who I have been dating awhile now. We are taking our time with things but from what I know now, I think we will have a good future.
Our conversation recently turned to marriage. I was married for 12 years in the past and divorced about 5yrs ago. I am scared of telling him about this because his family is very traditional and I worry he won't want me after he knows I am divorced. Does he have to know that I was married and now divorced or would I be allowed to declare myself single when the time comes to fill out the necessary forms for our marriage? I am terrified of losing him simply due to culture and tradition. Please help? Advise? Thank you.
