This 42-year-old man and his 40-year-old Wife have one son together named Frank, and Frank is 18-years-old.

He went to college with his wife’s younger brother, and his wife’s younger brother introduced him to his wife.

Five months before Frank’s due date, he found out that his wife was pregnant, so his life changed pretty quickly.

Since his wife’s parents are ultra-traditional and promised they would cut them out of their lives if they didn’t hurry up and get married, he agreed to marry his wife.

He and his wife have never had an easy marriage, but they have remained together for so many years for Frank’s sake.

“As Frank got older, I started to notice his features, how none of them matched mine or my wife’s; we both have short noses, whereas my son’s was always particularly long; we are both dark-haired with darker skin, whereas my son is a very fair blonde with freckles and skin that is so pale it’s almost translucent,” he explained.

He wasn’t exactly bothered by Frank not resembling him or his wife, and he figured that as Frank grew up, perhaps that would change.

But when that never happened, he began to grow suspicious, and he asked his wife if there was any chance that someone else was Frank’s biological father.

His wife maintained there was no way Frank could have been fathered by another man, and he trusted his wife.

Several years after that, Frank got a girlfriend and brought her home to meet them. He and his wife pulled out a family photo album to show Frank’s girlfriend, and as his wife flipped through the book, he kept seeing a man who looked exactly like Frank.

He asked his wife to turn back to a particular photo of this man, and his wife slammed the photo album shut, saying she needed to go finish up dinner.

For the remainder of the evening, his wife hung onto the book and wouldn’t look him in the eyes, so when she finally fell asleep, he grabbed the book and went back to look at all the photos of this man.

As he looked at the mysterious man, he couldn’t help but notice that all of his features were just like Frank’s. His jawline, his mouth, his eyes, his nose; they all aligned.

“When I confronted my wife about it in the morning, a screaming match ensued, our neighbors ended up calling the cops, and I spent the next two days in a hotel in town,” he said.

“I asked my wife to meet me for coffee, where I gave her an ultimatum: she would either agree to take a paternity test, or I would file for divorce.”

“She broke down crying in the middle of the restaurant and confessed that the man in the photos was, in fact, Franks’s biological father and that he wanted nothing to do with her or her baby.”

His wife admitted to baby-trapping him with Frank, knowing that he would be able to find a great job and provide for them after graduating from college.

He was sad and humiliated to hear that his wife lied to him for close to two decades, but what hurt him the most was finding out that Frank knew he wasn’t his real dad for the last four years.

So not only did his wife keep this a secret from him, but Frank hid it from him as well.

“I called Frank and confronted him about keeping this a secret from me, and he told me that he simply didn’t want to give up the life we had and the financial stability I gave him and his mom,” he continued.

“He was planning on telling me after I paid his college tuition. I blocked his number and filed for divorce from my wife a few weeks later. I’m currently at my parent’s house while trying to find somewhere temporary to stay.”

“I’ve received many angry messages from my wife and my family telling me I’m a horrible person for cutting off Frank, even if he’s not my own son. I don’t think I’m in the wrong, but I don’t have anyone on my side here, and I’m starting to question if cutting off Frank was maybe too far. What do I do?”
