Get a prenuptial agreement or don’t marry a woman with no moral respect for anyone but herself. (Yes there are exceptions to this.) But I’ve seen too many men and women choose partners that are obviously terrible human beings, then go full surprised when that person ruined their lives. I have a friend that is still paying for her ex-husbands life style. I feel bad but all of her friends and family told her not to marry that guy but she doubled down and is on the hook until he marries again.
