After a contentious reaction to her pregnancy announcement, Sadie threatened to cut Bella* out of her life.
Bella – a 22-year-old university student – is surrounded by LGBT friends who are in queer relationships and, according to her, "there is rarely a pregnancy scare".
In the 10 years that she has known Sadie, 31 (a heterosexual woman), the mother-to-be "has never had a serious or long term relationship".
"She has always said she never wants kids and never wants to settle down," Bella wrote on the sub-reddit r/AmITheAsshole.
"Two weeks ago we didn't talk for three days and I was getting worried about her," she continued. "Then she texted me, randomly at 3am: 'I'm pregnant....'."
Here's where the controversy starts. Given this context, Bella's first instinct wasn't to offer congratulations, but rather to gauge how Sadie was feeling about the news. She reacted with surprise and curiosity rather than immediate celebration.
"I responded 'Oh shit! Are we happy or sad about this? Who's the father?' Because I didn't want to celebrate too soon as everything I've known about her makes me think she wouldn't be happy about this," Bella explained.
She didn't hear from Sadie for 24 hours, until the 31-year-old called to "chew (her) out".
"(Sadie asked) why couldn't I just be happy for her and that it is really rude and disrespectful to ask the questions I did," Bella wrote on reddit.
