My husband and I have been married for 25 years. His mental illness is becoming too much to handle for me; he will not take his meds as prescribed and has been verbally abusing me and our home (smashing things, etc.). It has also recently come to light that he has cheated on me, once that I know about, could be more than once however. We are both 62 years old. I want to file for divorce. My question is, I have a 401K retirement that is worth about 200K; I know WI is a 50/50 state, at least that is what I have been told. Is he going to get half of my retirement then? Even though he is abusing me and has cheated on me? He has a small retirement, about 30K, would I get half of that? We do not have any children.
