After divorce, will his bad credit affect me?

My husband and I were divorced. We never had any credit cards or loans in our names jointly and in the divorce decree, we were each given responsibility of paying back our individual credit cards and loans. Since that time, he has gotten behind and/or stopped paying several of his credit cards and loans. Can this affect my credit even if my name was never on them? There was one card that I was an authorized user on but it was never considered a joint card and I was removed as an authorized user prior to the divorce being finalized. If they don't even have my social security number, can they still come after me or affect my credit negatively? Also, if he files for bankruptcy and the debt is written off, can they come after me, again, having never had my name on those debts?
