I found out my dad is cheating on my mom, so I told her. My father blamed me for being a home-wrecker and trying to start problems. The issue was eventually resolved between them, but once again, a year down the line, I found out that he is still cheating on her. I didn't want to get involved because I'm not sure what the right thing to do is in this situation, but I did eventually tell my mom, and she stopped talking to him. Then, she spoke to a priest who advised her to speak to him and to come together. I know my dad will not stop his ways so should I keep fishing for information or just let it go? What should I do if I find out again?
What you did to inform your mom was not wrong. She has the right to know. It may have been better to consult with your confession father or your mom's confession father before revealing this sensitive matter to her in order to discern the manner in which such a message should be delivered. It is not just a matter of revealing the truth, but because there is much pain and anger that will naturally follow the betrayal of a loved one and the broken trust, a spiritual support system needed to first be in place for the repercussions. Having said that, if your father continues engaging in adulterous relationships, confide in the clergy. There are many reasons for this kind of reckless behavior and perhaps the clergy may be able to lead him to repentance. They have the obligation and are endowed with the wisdom to discuss the matter with both of your parents, not only from a spiritual perspective, but also as a duty to warn as your mom may also be in jeopardy of contracting STDs because of your father's extramarital affairs.
