Hello Greg and God bless you. I am a devout catholic who saw my own marriage end in the failure of divorce and I later had an annulment granted by the catholic church. I have not since remarried, but I was plagued with doubt and guilt before, during, and after the divorce process until the end of my annulment process. Your friend has my sincerest sympathies and prayers. The idea of divorce is not only emotionally traumatic, but as a catholic, it can be spiritually crippling and leave one overwhelmed with feelings of guilt and remorse. Your friend will question everything, from “am I doing the right thing” “why is this happening to me” “how could things be different” and “could I have done more”. The best thing you can do for your friend is be supportive and pray, pray, pray and entrust this situation to the Blessed Mother. Offer a mass for her if that’s what it takes, but do not encourage her to do anything or commit to anything as serious as divorce or separation without seeking the counsel of a priest. He will offer his advice, and possibly even marriage counseling or suggest a counselor. If her husband is unwilling to go with her or speak to the priest or counselor, as my husband was, then, and only then after much prayer, it might be time to be seeking other avenues, but she must above all surrender the outcome of this situation to God and allow his will to be done. The threat of divorce might have been looming for a long time in this marriage so she might have had lots of time to think about this, but if she places her trust in God first and foremost before acting on anything and seeks a priest to consult, her conscious will be at a much greater ease with whatever outcome the Lord choses and she can rest easy knowing that the Lord has blessed her for placing her trust in him.
