If one’s husband has a vasectomy without even asking the other spouse about it - is this legal grounds for a separation, as now it is not a valid marriage since the couple is not now open to procreation?
The validity of a marriage is determined by the couple’s ability to make an honest and well balanced adult decision at the time of the wedding–and not later. The dishonest and sinful behavior of the husband here is a serious matter, but it cannot invalidate the marriage. I don’t know enough about the people involved to comment on the advisability of separation.
