The answer
Just as you have experienced, ending sexual relations is not easy. For that reason, it is clear why this young lady had several encounters with men with whom she was in relationships. This became a normal aspect of her relationships, and in which you also participated, albeit, the Church teaches that sex before marriage is prohibited. Therefore, you both need to repent and confess, even if you decide now to remain celibate.In regard to her previous relationships, it seems that you are very bothered by knowing about her past, especially because sexual activity was repeatedly involved. Do not judge her for the same sin that you willingly pursued and to which you willingly contended. Neither of you can undo the past. You have a choice to move forward from here, either together or apart. Whether together or apart, you both need to confess these sins and receive absolution from your confession father(s). Also, your age is an important factor? If you are young, how can you make a commitment now for marriage? Absolution will provide you both with a new beginning void of those past transgressions.
