F2 pending, husband leaves the sponsoring company, what happens to my pending status f2?

Unfortunately, your husband is the lead and you are only in the position of the derivative. USCIS by law is not supposed to approve applications for derivatives where the principal has left the country. If you are able to apply for another visa status such as F-1 student and if that is approved, you may be able to stay independent of your husband.
