I know that but a private committment can be just as much of a committment as a public one. The committment depends on what is being promised and how sincere that promise is. If it is private it may not gain recognition, but it’s still there and God knows it’s there.
Besides in canon law, it is allowed for couples to do it privately in exceptional circumstances, namely in danger of death and literally when being Lost like on that island in Lost without a priest or deacon:
Can. 1116 §1. If a person competent to assist according to the norm of law cannot be present or approached without grave inconvenience, those who intend to enter into a true marriage can contract it validly and licitly before witnesses only:
1/ in danger of death;
2/ outside the danger of death provided that it is prudently foreseen that the situation will continue for a month.

As long as you think you’ll be stuck on that island for at least one month
Well then, feel free to not marry if you’re in danger of death or if you’re stranded on a desert island. Actually scratch the desert island idea - you need WITNESSES, not just the two of you. Which kinda makes my point - at the very least it MUST be publicly done, in front of witnesses.
Neither of those exceptions apply to you in any case - and if they DID you’d probably find you’d be obligated to marry in church afterwards, if you survived your illness or were rescued from the island or what have you. They’re stopgap and exceptional measures, not ordinary rules for conducting a relationship in ordinary circumstances.
And my commitment to my mother can be just as strong as my commitment to my spouse - doesn’t make me married to her.
Marriage is a public commitment, it’s an inescapable and important part of its very definition. If you haven’t committed in public your relationship is fundamentally different in nature to marriage - the law recognises that differences, as does the Church.
As Genesis shows (the passage I quoted in my last post) even God recognises the difference, since it is only a wife, not a fiancee, who is to become one flesh, and only with her husband, not her fiance.
Anyway even if sex before marriage is imperfect, at least once you are married all that is blessed by God retroactively if you will. It’s not like He doesn’t want you to remember those moments with fondness. I’m sure you’ve seen the movie The Notebook. Do you really think God would want that couple to not remember with fondness and thanksgiving to God those memories of their premarital love making as well as all the other premarital memories? If we can remember those things with fondness, then it can’t be wrong to have done them; otherwise, we would be called to remember those things with regret.
This seriously is the biggest load of bs I’ve ever heard. God does NOT bless our sins retroactively. Pre-marital sex, whether it’s five minutes before or five years, is WRONG. And the mere fact that you ‘remember it fondly’ - means less than nothing. You’d probably remember ANY fornication or sexual sin fondly and without genuine regret - adultery, homosexual sex, bestiality, incest, you name it. Doesn’t make any of it right, or blessed by God, retroactively or otherwise.
God doesn’t want us to remember ANY of our sins fondly - and certainly not to blaspheme by thanking Him for them!
Rather they should be repenting that they so disrespected His holy sacrament of marriage as to presume to rights to each others’ bodies that belong ONLY to those who’ve taken their vows sacramentally in front of HIS minister and declared their commitment to each other in public.
