Divorce is a touchy subject among Catholics in Massachusetts and the rest of the world. In fact, disagreements on the subject of divorce caused many other denominations to spring up and separate from the church, perhaps most notably, the Anglicans. This is because the Catholic church generally treats marriage as a permanent arrangement unless the spouses receive an annulment.
USA Today explains that in the Catholic church, for an annulment to take place, a church tribunal must declare that a marriage once considered valid actually failed to meet at least one essential criteria. Without this, separated or divorced spouses cannot remarry. The church may consider a Catholic who remarries an adulterer as the new marriage is not valid and the old one is technically not resolved by its standards.
