From my own personal experience (twice divorced) it was me who initiated the divorce due to extreme unreasonable behaviour, like cheating and narcissistic, toxic, physical violence. It surprised me that you did not seem to cover what I believe to be one of the main reasons women initiate divorce and men less so, is that the law over favours the women. She gets custody of the children, the house, all the furniture, financial support for her and the child/ren. The man loses everything, which he is in no hurry to do.
