"Sometimes I have issues with jealousy, and I hate that you got all of the high school stuff with him. You got to go to games and support him. It kills me that I couldn't be there for him because I know I would have actually been there wholeheartedly. I would have done it out of love, not as a popularity appearance."

Echoing much of the public reaction, Britain's Daily Mail headline referred to the essay as "scary."

One woman defended Higgins in the comments section of the essay.

"It's sad to see so much hate in every comment," she wrote. "Everyone gets jealous about something. I find her courageous to talk about that something did make her feel that way because it is hard to let people see you vulnerable.

"She never called the other women nasty words or disrespectful. Some of you should be ashamed of the things you said."

Another was reminded of her younger self.

Higgins wrote to her fiance's old girlfriend that she hated that she got to go to all the school dances with him.

"He got to see you all dressed up and probably told you how great you looked. I'm sure you did look great. Prom dresses were always fun to pick out and so colorful," she wrote.

"I try to not get jealous of all of the things you got with him because it is all in the past. You had your time, and now I get the wedding. You got to dress up in high school, but I get to dress up for my wedding with him. He may have put a corsage on your wrist, but he will be putting the wedding ring on my finger."

Of more than 40 essays Higgins has posted to the website since April 2017, only a few have been about her boyfriend and their relationship.

In an emotional post last October she wrote that she had been raped "by a guy that everyone at my high school knew."

That same month she wrote a thank you to the girls who didn't love her fiance "right," and one to "those who think I am too young for marriage."

"Not only is she so insecure that she’s jealous of the relationships her fiance had before she met him, she also thinks that marrying your college boyfriend is a ticket to eternal bliss," Katie Rife wrote for The A.V. Club.

"Coming from a divorced person: Bless your heart."

The Odyssey, meanwhile, seems to be embracing the story's popularity, even selling a T-shirt that says "Becky with the Prom Dress," a reference to the "Becky with the good hair" line from Beyonce's "Sorry."
