Well, it’s because both of them were adopted and weren’t aware of their true parentage.
Explaining in a post on Reddit, she wrote: “I just found out that I’ve been dating my biological brother for six years.
“I am 30 and my brother is 32. I’m just going to call him my boyfriend for the majority of the time while I type this.
“I feel weird about this. I was adopted as a baby but I didn’t know that I was adopted until I was in high school.”
She went on to explain that neither she nor her boyfriend/brother were aware that they had been adopted until high school.
Not only that, but she said their relationship was and is great, writing: “We understood each other very fast. We were attracted to each other quickly. I’ve never met someone and felt immediate attraction and familiarity.
“Now I know that the comfort and familiarity is because he’s my brother. Not my half brother.”
The anonymous social media poster recalled the moment she found out just how closely related they were, writing: “I was excited to see what we were but before I could even get to that.
“I saw that we were siblings. I was SHOCKED to say the least. I only just found out this information and I haven’t told my boyfriend.”
She continued: “We have a house together and a whole comfortable life. I’m hoping that this test is wrong and will do a real test soon but I’m panicking. I still see him as the love of my life.”
What would you do in that scenario?
