Settle in, this is a long story.

A would-be-bride has taken to the internet to ask for advice after discovering that her fiancé is actually her half-brother. And before you ask how such a thing could possibly be, it’s actually a very innocent story. The poster, who obviously wants to stay anonymous, writes: “We met through a tabletop roleplay group and had an instant connection. There was chemistry between both us and our characters and, as the campaign came to a close, he asked me out.” “It was a big deal for both of us. We're both nerds (as you can tell) and our social circles are pretty small. Both of us have trouble getting out there and socializing. We're more the type to keep our heads down. It was only my second serious relationship and his first. After a year of dating, we got engaged. We finally moved in with one another a month ago and our wedding is in six weeks. Beyond the normal little domestic naggings, things have been perfect. He's my soulmate. I don't know what I'd do without him.” Both the poster and her fiancé come from small families. “My father was never involved in my life and never was his family. I was raised by a single mother and her parents,” writes the poster. She always envied her boyfriend’s family who appeared to have a perfect life. “His mom and dad are great and the most giving people I know. His sister has become one of my dearest friends. They even sit down with eachother for Sunday dinners. Who does that? I've always been in awe of them.” But in the midst’s of wedding planning, the poster was shocked to discover that her boyfriend’s father was not his biological dad. “While working on wedding invitations - my future MIL mentioned that my fiance's dad is actually his stepdad. I asked to see a picture of his real dad and I nearly passed out when my MIL showed me a pic of my dad,” explains the woman. As if things couldn’t get worse, when the poster returned home to her lover, he revealed that he had known for about a year (insert shocked emoji here). “I got home and confronted my fiance about it. I was crying. I was screaming. He just sat there, fidgeting. Eventually, he admitted that he's known for a year but didn't want to lose me. Since we always planned to be childfree, he didn't see the problem with just keeping it from me,” she writes. Ending the original post, the author says that she is disgusted and knows there is no way for them to stay together. However, following some questionable advice from the Reddit community, the couple decided to give it a try. It didn’t end well. “Because the vast majority of you were so supportive, we decided to tell his mom and stepdad. It went horribly. They disowned him and cut him off; which is a huge fucking problem since they were paying for a portion of our apartment.” “The way they reacted was just a taste of how we feel others will respond, so we've decided to break up. However, before we cancel our wedding plans outright, we are going to speak to our father and take a DNA test. Thank you to everyone for their support and kindness. I just wish things had had a more positive end.” The weirdest part of the whole thing is that the majority of commenters support the pair and find nothing wrong with the incestuous relationship. “Huge difference between meeting unknowingly as adults and being raised as family. You have done nothing wrong. Maybe I'm way off base, but the biggest issue to me is that your fiancé hid it from you because it would upset you. Not a good precedent,” comments one Reddit user. Others don't even class it as incest. "Sharing DNA is not the same thing as being sexual or romantic with someone you grew up with. I can't blame anyone for not being able to think of it that way and I'm not positive I could get over it myself. But I wouldn't classify OP's situation as incest because I think knowledge/intent matters, especially considering how in love they are," writes another user.
