Knowing that a friend or family has suffered has haunted these Redditors.

A Painful Truth

"In the 70’s, my cousin died in a car crash that caught fire. I was very afraid that he was awake and felt the fire. My parents said he died immediately and didn’t suffer. My mother was on hospice at home in 2011. She told me the firemen were trying to open the doors and My cousin and the other teens were screaming for help when the cars caught fire. There were no survivors and my Aunt was never the same. It wasn’t until after his death that the jaws of life were distributed to our rural departments."

A Tough Call

"When I was 11 I had a friend reveal that her stepmother was abusing her... she made me promise not to say anything to my mom or any other adult. I agreed, we had weekly therapy sessions with a guidance counselor if you wanted it so it was my day to go and I just felt like I needed to tell… so I did. The counselor ended up reporting it and CPS got involved and my friend was made to live with her mother. She was so angry at me for telling but I felt it in my soul that I should. We are still friends to this day.. both of us 29 years old."

The Evil Of Addiction

"That he watched his son die of an overdose and didn’t do anything to help. He told me that his son had battled addictions for many years and that he had called an ambulance in the past when his son had overdosed, but that he thought it was better this time to 'just let him go since he made his choice.'"

The Ex And Her Health Issue

"I had an old girlfriend who was coming to Florida and wanted to hang out with me and my wife, she brought her mom, who I knew pretty well. A great dinner, drinks, fun stories, then when my ex went to the bathroom, the mom told me she (the ex) was dying of cancer. (I had No idea). It was sad, but yet felt so good she wanted to hang out. She died within a year. We were probably 35 years old at the time."

"You know..people will read this and grasp the sadness of the end but, on the other hand, your ex reached out and wanted to share some of her remaining time with you ..and your wife...clearly, your time together was special to her regardless of how it ended. You still had a warm place in her heart for you. That's actually quite awesome. I know you know that. Your wife is very lucky."

Life will never be the same after Redditors found out about these long-hidden family secrets.

What The Fork?!

"When I was 16, my Mom announced at dinner that her sister was coming for a visit next week. I dropped my fork and said 'YOU HAVE A SISTER?'”

–Initial_lampwick115

"I had this: age 11 driving up to Scotland with my parents and we stopped off at a tiny town, walked into the big hotel, then got introduced to my uncle. My mum's brother. Hadn't existed before then and only came out of the woodwork because my grandpa died shortly before (they didn't get on). It was a weird shock but also an 'OK cool, life goes on' moment."

Extended Family

"I'm 56 now but at some point in my early 40s while driving with my dad he says 'you have a half brother somewhere.'"

– ridobe

"My dad pulled this sh*t on me when I went to my grandfather's celebration of life. Picked me up from the train station, asked me if I knew about his new wife (I did) and their daughter, born six years before my mom died of cancer (they never divorced). Then had the guts to follow it up with a request to FaceTime them that night because they wanted to meet me, because "[he] never kept his family a secret... from them." It took a while for me to get over that."

Invisible Husband

"I found out my mother and father were not divorced. He never existed. She had a one-night stand, found out she was pregnant, bought a wedding ring, changed her name, and told the family that she had gotten married. She made up excuses every time she went to my grandparent's house as to why her husband couldn’t also be there to meet them. On the 3rd visit, my grandfather told her never to wear that ring in his house again and when is the baby due? I’m 53."

Why The Nun Made Weekly Visits

"I found out my parents weren't married when I was 14, and my parents had a massive row after my dad was caught by the police with a sex worker. My mum blurted it out to me along with the reason why they were arguing. I'm 50. Up til then, they pretended.. when my Catholic secondary school asked for a marriage certificate as part of my screening for the school, they sent a letter to the priest confidentially... I still got in. Explains why from birth until 11, a Catholic nun would visit my parents every weekend, probably to ensure my soul was intact, lol."

Things get sinister.

A Murder Confession

"Casually dropped they’d killed someone then got really quiet about it. Like, sad quiet. Sounds like there was a case surrounding the ordeal but could never get them to talk about it more and I didn’t want to push."

Dodging A Bullet

"My ex casual dropped he killed someone also. He was a lot more loud about it when he was upset with me though. 'I’ve killed for less'. I know the whole story, or both of them. The one he tells people, and the one he told me. Either way. He’s a scary man, and I would never wish to be near him again."

One of the hardest positions to be in is when a friend tells you that they've cheated on their significant other, whom you also know.

This happened to me.

Keeping the privileged information was agonizing as I feigned ignorance whenever I hung out with the couple or with the person who had been cheated on.

Eventually, the pair broke up as the affair came to light through no involvement by me.

The truth always has a way of surfacing, after all.

Would you rely on that to happen, or would you intervene?

When is it okay to betray the person who entrusted you with their secret?
