Is is illegal I know unethical, to mislead your wife of 35 years into believing that you have always filed a joint return when in fact you were not.

I have filed for divorce after learning of several very ugly things my husband has done, Upon going to the Social Security office I wAS told that could never file for disability due to the fact that there we're nog enough credits paid in on my account. I was a stay at home mom but I am also the co-owner of our families business which was started I'm 1989. We married in 85. If I demanded to see a tax return it would turn into a fight so I let it go for the sake of peace in front of two children. Now I'm learning how evil my husbands mind was working the last few years. I was trying to save our marriage!!
