My childhood friend cheated on his gf last summer with multiple partners. He just told me they’re about to get married and she still has no idea. My childhood friend Brandon and I grew up together and our families know each other. He’s like a big brother to me. He’s been dating his current girlfriend for 5 years.
Now, they actually are about to get married. I feel so bad for his gf but I don’t know if it’s my secret to tell. It feels like I’m sticking my nose into someone else’s business. But I also feel for the poor girl. If I tell her, our family’s relationship is doomed and my mom would definitely kill me for meddling too. Maybe ignorance is bliss? What should I do?
