Can I get a divorce based on his Felony conviction, also addressing mental cruelty and irreconcilable differences?

Husband incarcerated in 1999. Convicted of Class X felony in 2002. Got married 1 month prior to his conviction. He served 12.5 years and was released in late 2011. Within 5 months of him being home a break down of our marriage occured. Declined counseling, didn't want to look for work, etc. Won't sign divorce papers for 6 month waiver for no-faut divorce. Been separated since 4/2012. We have no kids, only property is a car and retirement plan on my job (job was stared in 2003).
