I have chosen to seek guidance/advice by utilizing the Catholic Answers forum for a couple of reasons. It has been a good source of guidance for me in the past and I have been unable to find adequate answers through my own research.
I will begin by providing some background, as my situation is somewhat unique (or so it seems).
When I first met my wife she was not a baptized Catholic. After we started dating she grew interested in the faith and ultimately made the decision to attend RCIA and was baptized. We dated for over 4 years before we got married, and we did everything right. We abstained from premarital sex, we lived separately (even though it would have been more convenient to live together), we attended mass together, and we frequently prayed the rosary together. We both knew the faith well and attended marriage preparation before we got married. Suffice it to say, we were well aware of what it meant to enter into the sacrament of marriage.
We were only married for 10 months when I found out my wife was having an affair. She left me for him and we got a civil divorce. She has since married him and they now have a child together. It has been 3 years since we’ve been separated.
Herein is where my dilemma arises. Should I seek an annulment despite believing wholeheartedly that we entered into a valid sacramental marriage? I recognize that I am not an expert in the matter but I have a good understanding of what constitutes a valid marriage and I don’t believe any elements were present at the time of our marriage that would declare it null.
Another question I have found myself pondering is a hypothetical one where a marriage is falsely nullified. We know that a valid marriage can never be dissolved, so if an inadequate investigation results in a valid marriage being declared null, what are the subsequent consequences?
