My wife and I divorcing. She's in Illinois. I've been in Wisconsin almost a year. We are approaching mediation. I learned my wife is seeking 75/25 split. I was blown away. I was thinking it might be 60/40, but 75???

In Illinois, which has equitable division, she may well get it. I just learned that I have residency and could file in Wisconsin, which would mean 50/50.

My question, is this taking care of myself, or a major dick move? I honestly would concede to more like 60/40, 75/25 feels unfair and like shes placing hardship on me. I have always felt like I was invalid in our marriage and I got walked over for years. Made to feel like I was dumb. This feels like standing up for myself. I want to be taken seriously. But I'm scared and feel sick to my stomach.
