How mad would you be if you just found out that your husband never filed his taxes his whole entire life?

My husband never filed taxes his whole life and never told me. We always kept our finances separate since we had been married before and there had been issues with former spouses. The IRS caught up with him and had been garnishing his wages and he still didn't tell me. I made him fess up after I noticed he wasn't buying as many groceries as he had been. We had made an agreement years before that he would buy the groceries, utilities and car insurance when I graduated from college and started working but those were are only bills. We each paid our own car payments and I paid my student loan. Then over the years I gradually picked up more and more of the expenses since I earned a "little" more than he did. I picked up the mortgage, the home insurance, the property insurance, the health insurance, the propane bill, the property tax on the farm, medical bills, dental bills, orthodontic bill for two teens, hospital bills, extra groceries, vacations, entertainment, extra taxes, car repairs for me and him, farm animal purchases, vet bills, hay bills, fence supplies, well repairs bills, home repair bills, furniture purchases, family clothing purchases, home improvements, landscaping improvements, decor improvements, travel, gifts, wedding gifts, birthday parties, basically every family need or want over and above basic groceries, utilities or car insurance. I asked him over the years to please pick up some extra work in his field or a part-time job to help with his garnishee expenses. He said "I'm not going to miss that time with my kids. I'm not going to do it." For almost four years he goes to work and comes home and plops in the recliner. He is a great dad. He is an affectionate and attentive husband. But he won't work extra and won't help with housework or home repairs, car maintenance, car cleaning, yard work, etc. I work nights and feel like a zombie a lot and if I want to go out or do something I have to go alone or find a friend or BEG him to go and pay for it myself. What is wrong with him? So we had a big fight about money AGAIN and he moved out and insists on a divorce. He is furious that I am asking for child support to help with all my debt. I am left here alone and mad and he says it is all my fault. How would you feel?????
