Filed bankuptcy but lender has nt foreclosed Am I liable?

I filed for BK in Dec 2007. Although i moved out in Jan 2008 my ex did not until we surrendered the home July 2008. The bk was discharged in June 2010. My ex-husband found via the web that the home is still in my name and that the bank still did not foreclose on the property. He says that i will be held liable for taxes and reporting it as income if i do not initiate a short sale with the bank via his office (currently working in a real estate ofc). says I need to avoid letting them foreclose on the home. I have not received any 1099 to my knowledge and did file taxes each year. Am I liable for paying any taxes or deficiencies? I had no idea that the bank did not proceed with foreclosure. I had assumed it was already reported to credit bureau as foreclosed as well as the bankruptcy being reported. To add insult to injury, I cannot seem to locate the attorneys who assisted us with the BK filing.
