This gender reveal party certainly didn’t end well.

A 33-year-old man and expectant father said that he suddenly left his unborn baby’s gender reveal party after learning the child would be a girl.

“I don’t know what came over me but all I felt at that moment was very bitter disappointment,” the man, with the username delaputa said on Reddit’s “Am I the A--h---” forum last week.

Delaputa, who said he already has a 5-year-old daughter, explained the story, starting with the fact that his wife has “been grouchy her whole pregnancy so her sister offered to plan her a gender reveal party.”

According to his post, the baby’s gender would be revealed when the couple lit a sparkler, turning pink if the child is a girl and blue if the child is a boy.

When the sparkler turned pink, he said, he felt “very bitter disappointment.”

“I know my daughter is only five, but I’ve already started to deal with the dramas of being a father of a girl and the thought of having to double up now on the neuroticism was harrowing,” he added.

The Redditor also said that having grown up in a house with three older brothers and a younger sister, he “can’t imagine seeing myself be outnumbered.”

After finding out his second child would be a girl, delaputa said his wife told him to “look happier” as party guests were coming to congratulate them, but he said he couldn’t.

“At that moment I just snapped,” he said. “I shook my head and walked out to my car (we came separately) and drove to my sister’s (21F) house.”

However, many commenters were not thrilled with delaputa’s story.

“No one is stopping you from tossing a ball with your daughter, or from camping with them, or encouraging them to participate in sports,” one person commented. “You are the one stopping them from this.”

“My thoughts exactly, doesn't matter what gender your child is born, you can still play games and bond,” another person wrote. “The problem here is OP's attitude to girls/women in general.”

Someone else said: “The misogyny sprinkled all throughout this post is astounding.”

Another commenter wrote: “Also... Some boys hate playing catch, Little League, Boy Scouts, and camping trips. I know a lot of guys who aren't interested in those types of things when they were young.”
