Cont'd sponsorship obligation following divorce

[smileys]

I am american and was living abroad, I came back to the US with my husband (non-american). We separated a week later and got divorced 6 months later. To come to the US, I had to sponsor him and he got a 'green card' good for 10 years. Do I have continued sponsorship obligations? If so, what are they exactly? Is there any circumstance whereby I am no longer obligated such as he gets remarried, he leaves the country, etc.
Thanks.

According to the USCIS "Your obligation to support the immigrant you are sponsoring in this affidavit of support will continue until the sponsored
immigrant becomes a U.S. citizen, or can be credited with 40
qualifying quarters of work in the United States. Although 40
qualifying quarters of work (credits) generally equates to 10
years of work, in certain cases the work of a spouse or parent
adds qualifying quarters toward eligibility. The Social
Security Administration can provide information on how to
count qualifying quarters (credits) of work. The obligation
also ends if you or the sponsored immigrant dies or if the
sponsored immigrant ceases to be a lawful permanent resident
and departs the United States. Divorce does not end the sponsorship obligation."
