Wisconsin - legal separation? Is it possible to completly separate finances legally, without getting divorced? My spouse has an alcohol addiction andhas been arrested several times for drunk driving. I'm afraid that he may kill someone someday and I will be legally responsible. I need to know how to stay married, but untie all our finances. I am the breadwinner, and he is in jail most of the tim. However, I would like to keep my health insurance coveragea on him, as he will need it.
