This 21-year-old recounts a truly traumatizing experience where they ended up "ratting out" their mom for cheating on their dad who was on away on military stuff. Apparently the guy staying with his cheating mom was claiming to play a role of "protector" while their dad was away. Talk about swinging low, man. That's just terrible. 

Text - r/tifu + JOIN u/mlenarcheck - 7h TIFU by asking about my parenta divorce and found out I contributed to the divorce. Okay, first off, my parents have been divorced for 12+ years. I am 21 now and was 7 or 8 when they split. I found out a few years ago it was because my mom was cheating on my Dad with my nurse from the NICU from 1997 (oof)
