Based on the information you gave, I find it highly unlikely your husband can terminate your visa. Note however that you are a green card holder. As such, CIS may terminate your green card where it finds that you have spent 365 days continuously outside the US. If you have been away from United States for more than 1 year, you should contact an immigration lawyer before returning to this country.
