A 25-year-old woman took to Reddit, where she could post anonymously, to rant about the drama in her life.

The Boston native began: My father married my step-sister’s (23F) mother when I was 4 and she was 3. We’ve lived together most of our lives and are a family. She and I were extremely close.

“She developed cancer when she was 14 and was sick for about 2 years. She’s since made a full recovery.

“During that time, my parents became understandably over-protective. They also asked a lot of me. I quit my extracurriculars so I could get a job (the money went towards her medical bills) and so I could drive her to appointments.

“I didn’t go to dances and any fun activities I did needed to include her. I did almost all of this willingly, the exception being having to quit my high school volleyball team – I did throw a bit of a tantrum about that, but was swiftly punished. And I think having one emotional breakdown was pretty chill given the circumstances.”

She then explained that when she went to college, she met a man whom she named Ben to protect his identity.

They began dating in their third year of college and moved in together after graduating.

They had been living together for three years.

“We were serious until July when I walked into my bedroom and saw him f**king my sister,” she revealed.

Of course, she ended her relationship with Ben and he moved out. Her sister also apologized for the way things went down.

She continued: “I thought she was giving me space but last week she called and asked if we could meet up. She told me that she and Ben were in love and were just telling me as a courtesy before they started posting photos online.

“Distraught, I left her in the restaurant by herself and did not pay my portion of the bill. She later venmo’ed me asking for the money.

“She told my parents who then called me to their house, telling me how disappointed in me they are for not supporting my sister’s relationship with Ben.

“They brought up the fact that because she had cancer as a teenager, she never learned proper social etiquette, and has a hard time meeting people. I don’t buy this, in part because I’ve seen her socialize just fine and since we spent a good chunk of the time she was sick together, that would also mean that I should have bad social skills as well, by that logic.

“They then told me that if I don’t accept my sister and Ben’s relationship, they may have to go no-contact with me. I reminded them that I’m also their daughter and they should understand my point of view, but they are adamant that this is about me being jealous of her.

“For the record: I’m not jealous of her. I’m not upset that Ben picked her over me. I’m sad about the end of the relationship and do feel betrayed, but lord knows that I don’t want to be with a cheater.

“What I’m upset about is the fact that my sister chose Ben over me. That she slept with Ben knowing he and I were in a long-term, committed relationship, and continues to be with him knowing how much it hurts me.”

She later added as an update: “Turns out my sister is not only in a relationship with Ben but FOUR MONTHS PREGNANT. This means she and Ben were f**king for longer than I had even guessed.

“Apparently, my parents are so adamant that I forgive her because I’m already ruining their experience of their first grandchild. That’s right, I’m less important than my stepmom posting ultrasounds to Facebook. This is where we’re at.”

Following an overwhelming response from Redditors, the woman posted yet another update after speaking to her sister once more.

She said: “I got in touch with my sister and asked her to meet up again at a park (no bill involved). I asked her if she was pregnant and she told me the truth. She said she wanted us to still be in each other’s lives and that she wanted me to be in her baby’s.

“A Redditor (and I forget who, I’m sorry) mentioned that she may ask me to be the godmother and that person was correct. But as many of you pointed out — if I didn’t cut her off, I’d just become her bank and daycare employee. So I told her I could no longer be in her life. And I left her crying on a park bench and felt like the s**ttiest person in the world.

“I emailed my parents and told them how betrayed I felt and that I’d be cutting off contact with them. To my stepmom’s credit, she apologized. She explained that she never thought my sister would live to have kids and that she let her emotion over that get the better of her. Understandable.

“My dad said nothing, which is honestly what sucked the worst about all of this. Ben tried messaging me from a burner account for the first time since the break-up but I blocked him without reading it.

“I didn’t go nuclear and post the story to Facebook as some suggested but I sent an email to the extended family members who I care about. I explained the situation and how I’d be distancing myself from my family.

“Some have made it an us-versus-them situation and as much as I appreciate the support, feeling like I’m in some valiant battle just makes me more tired. So I haven’t been talking too much to anyone in my family.

“I feel lonely and crappy, but I think I made the right decision.”
