See if you want peace then I would suggest mutual Iu2019ve seen people fight it out like cats and dogs in courts who eventually settle mutually because they are tired of the shit! However there are a lot of the strong willed ones who are bent upon making the life of their respective spouses resembling hell, and they manage to do that. But what I feel in this whole process you loose out on yourself your own happiness. Especially with a child involved you might want to make it easier on yourself. Rest you know your situation better. Life is too short to waste on unwanted shit move on live happy.
