Generally speaking, simply marrying a person with a poor credit history will not damage your credit. The only way that I can foresee your husband's poor credit affecting you is if your husband added you as an authorized user on any of his accounts with a less-than-perfect payment history. If he added you to any of his accounts with a delinquent payment history, these accounts could appear on your credit report, thereby damaging your credit score.
On the other hand, you may be able to help your husband improve his credit score by adding him as an authorized user on some of your credit card accounts, or by co-signing on a small loan with him, such as an unsecured personal loan. You can use your good credit to help your husband establish new credit lines, which should have a positive influence on his credit score.
