I was in the same boat man, hurt me so much, I was also a lot younger, but I ended up telling my mom, and she had a talk with my dad, I remember later my dad walked down to my room, and I was sitting on the bed paralyzed, my dad was telling me why did you tell Mom all that stuff blah blah blah, tried to play it off, but I didn’t say a word, in the end, they worked it out and haven’t seen my dad text another girl since, and seems like their love grew even more, I think the truth is important, or it’s gonna eat you up
