That’s true, but many good Catholics can sincerely come to believe that there is no valid marriage and obtain an annulment. I don’t know to be honest how easy or difficult it is to get one, but there are certainly plenty of people who do this without going against their religion.
There is absolutely nothing wrong declaring a marriage null
when it’s null. In fact, sometimes letting it rest would be no solution because convalidation would be required. It’s true that there are some stats showing that around 90% of American nullity decrees are reversed by Rome on appeal (this doesn’t mean 90% of nullity decrees granted, it means 90% of the appealed ones), in which case your skepticism is understandable. However, the sacrament of marriage is a consensual “affair”. You can’t effect it by words alone. There’s no valid marriage under force or by fraud. Same way, if someone is in a severe mentally debilitating condition, that’s no marriage because the person just can’t make the promise he’s trying to make. There’s nothing wrong in not insisting that those people do live together or stay unmarried in the practical sense or something like that.
I am skeptical that just because someone is a faithful Catholic it means they are unlikely to leave you. It would be interesting to see statistics on this. The statistics that I’ve seen show Catholics not being any less likely to divorce, but that of course includes cafeteria Catholics who are the majority.
Yes, I dislike that fact. I also dislike nullity decrees given for light reasons (in which case, if the tribunal is wrong, the result is material divorce with material bigamy and material fornication following). But in the cases where it’s obvious or proven that at least one of the persons attempting to marry did not have the capacity to marry at the point of exchanging vows and there was no convalidation later on (just because someone excluded children at the time of wedding but changed mind later on doesn’t mean the marriage is invalid right now), then I believe it would be wrong to force or expect people to stay together. Convalidating such a marriage if possible might be morally superior to splitting up in some cases (and morally safer, perhaps), but it’s the parties’ right to split up if they have no valid marriage.
I wonder about this, I guess I’ll have to see how my relationships are affected in the long term. I have had several “crushes” and casual relationships lately, but none where I was “in love”. Maybe I’m just fooling myself and it’s impossible to be in love and not dependent to some degree.
If you really insisted on using medical terminology without any respite, I suppose you’d have to say that being a love is technically a psychosis. Anyway, it’s possible to have a normal, healthy, loving marriage and family without being dependent in a medical sense. But there’s nothing wrong in depending on each other or needing each other in a normal human sense. A similar, although closer, sense to the one in which you need the cops, the hair-dresser, the plumber, the attorney (well, let’s hope you don’t need that one), the doctor (again), the teacher… Even if you pay them, you still need them and they need you because they couldn’t feed their families without working for you for money. You
can live without them, but it would be all the harder. Same with a husband or wife. You won’t die when he or she is no more with you, and, “I couldn’t live without him/her,” is a metaphore only, but on some occasions you may and probably will depend on him/her for a living or for life itself. You may have to trust that person with it. If I couldn’t give a woman a blank cheque or my only credit card with a code, I wouldn’t marry her.

If you can’t leave a guy alone with your friend… same thing. Now, if a lawful wife actually asked me to give her a blank cheque up to the whole sum in my account, I would surely ask what it were for and she would have to do a lot of talking before she got it. We’re not expected to be naive.
