If I were in a PVS for more than a decades because the courts wouldn't allow my wife to remove the tube, I'd want her to move on with her life.
How sad. My husband and I married for better or for worse. That means whatever comes at us.
So you would want your wife to stay married to you while she lives with and possibly has children with someone else? Isn't that kind of selfish of you? Wouldn't it be better to let her divorce you and marry the other man and give her children a proper home?
