… My dad is married and I just can’t tell my mom. She is so kind, caring, loving, and fragile. If I confronted him and told my mom, it would break her heart. I love my family and I just can’t stand the fact that this is happening. Please pray for us…
I stand by my first comment that the OP should first ask a priest about the morality of using information which was obtained by reading private correspondence. But, given that, I have something to add.
The word “fragile” has been going round in my mind since I first read this, and I feel now that I must post my thoughts.
What I am about to say IS ONLY HYPOTHETICAL. I am certainly not trying to diagnose a marriage beyond the little info we have in the OP.
I was married for ten years and I throughout that time I saw my wife as “kind, caring, loving, and fragile” and I think that any outsider would have seen the same, and our children too. It was only after my wife left me (for another man) and wreaked havoc on myself and the children that my eyes were opened. Throughout our marriage SHE WAS THE BOSS!! She had a will of steel, often feigning “fragility” (tears and temper) to get what she wanted, by making me feel that I was an ogre unless I gave in to every demand.
How is this relevant? If it applies (and that is a big “if”) then the very worst thing the OP can do is tell mom, as I’ll now explain…
If this picture applies then I expect the husband is miserable and doesn’t know that the source of his misery is an unhappy marriage. He has spent years trying to please his wife, and all he gets for it is increased demands. Recently he has met someone who makes him happy. But, he is a Catholic, and he is going thru turmoil, knowing that what he is doing is wrong. Hopefully, he will decide to reject the temptation and stay with his wife and family, and, eventually the other frictions in the marriage will take their course. But, if the OP tells her discovery to her mom, and her mom then confronts him, he will be completely crushed. Every shred of dignity which he had left will be taken from him. The decision that he might have made on his own (to be loyal to his vows) will now be forced on him. He will also have been deeply shamed in front of his wife and daughter, and his domineering wife will have ammunition which she will use to keep him in his place for the rest of his life, and give her licence to be unfaithful herself (maybe sexually, or maybe another way).
Again, only hypothetical, but it can be read into the OP scenario. It is a “worst case” outcome for the consequences of telling her mom, but I think it is also realistic and possible. If it matches then the best thing is for the OP say nothing to mom, and probably not tell dad either, but let things take their own course.
But it is unlikely that the OP is in a position to diagnorse her parent’s marriage, and nobody here is either, which would then go back to saying nothing as the default position.
But, please ask a priest. As lebe said, above, “He probably won’t “tell” you what you should do, but it will help clear your mind and you’ll feel better getting it out.”
