filed chapter 7

my "at the time" husband...and i filed chapter 7 in 2007..our attorney would not allow us to reaffirm any of our debts including our home.... a year later my husband left me and the court awarded him the home...he has since walked away from the home...with the mindset that the house was not reaffirmed so there would be no extended loss by walking away...my name is still on the home... i have since been served and apparantly being sued by the mortgage company...is this just the process they have to take or is something wrong here...is my current home in jeopardy of being lost due to this
