Questionable behaviors were seen as major turn-offs.

Poor Parenting

"The way she treated her children, her boy was permitted everything and her daughter had to follow very strict rules."

"I didn't have to ask to know what was going on, the boy's real father wasn't her ex-husband but a guy she had an affair with at work, her daughter was really from her ex-husband. She was always resentful of her upbringing and then her marriage for impeding some kind of dreamed life she thought she was entitled to. So the boy was seen as a piece of that dream and the girl was a piece of her boring life but she was also reliving her childhood through her and pushing her to excel in sports, school and manners and reveling in her daughter's accomplishments as if they were hers."

Past Grievances

"She accused me of cheating on her in a past life."

"I told her 'I don’t remember that.'”

– Breloren

"Sounds like something someone who cheated in a past life would say!"

At Least She Washes Her Hands...

"She spat in her hands and rubbed them together because she 'needed to wash them.' I cannot describe the colossal speed at which that switch turned off."

– whitesebastian

"Was she some sort of 1930’s farm hand or construction worker?"

– valueduser

There were some serious red flags.

Schadenfreude

"A elderly gentlemen fell in front of us, he took a nasty fall."

"She found it hilarious, instead of helping she just stood there laughing. I helped that person out and I felt so embarrassed for her behavior."

"Also that was the last time I saw her. It was a major turn off for me."

Good Guy Vs. Bad Guy

"I invited the girl from my psych course I'd been vibing with to a party. Her car rolled up and I came out to greet her, but it was a dude's car, and she was drunkenly making out with him as I walked up. I didn't flip out or anything, but she slurred her way through some weird attempt at reassuring me that I shouldn't worry, 'cause she was only sleeping with him to punish him because he was a bad guy (apparently that's a thing she does), and that I was a good guy. I didn't ask what happened to good guys. I felt bad for her date, whom she completely ignored the rest of the night. As for the girl, she ended up totally engrossed with the party host's gerbil, tapping on the glass of its cage whispering how she wanted to kill it. I found somewhere new to sit in psych class for the rest of the semester."

I'm Generous And You're Gonna Like It

"She kept buying me stuff. It was nice at first but she kept doing it weekly and demanded I give gifts in return. I asked her to stop and she said "nope this is what I do." Felt like she didn't even care about what I wanted."

Easiest Breakup Ever

"It was a really horrible relationship even this aside but my 'wow i think i actually hate this person' moment was when we were at Badlands National Park. We were just walking out of the gift shop with some other woman when she just let go of the door and it like slammed into that womans face. I said to her 'omg im so sorry' then when we got to the car i said to my gf in like a joking tone 'i cant beliehe you didnt hold the door for her haha' and because she was a very very miserable person all the time this makes her mad and she goes 'well YOURE the man youre supposed to hold the door. I dont NEED to hold the door for anybody' and yeah that one statement alone was very... eye opening for me."

"Seriously the easiest least heartbreaking break up ive ever gone through."

The Cat Recognized Evil

"My cat didn't like her."

"Brought her home to introduce her to my parents, she meets my childhood cat and. It. Goes. Psychotic. Just for her reaching down to pat him, he panicked, attached himself to her arm, and wouldn't let go, just clawing at her like he found a demon to fight or something. When he eventually detached himself (they were both running around the room screaming as she tried to wave him off her arm) I checked her over and he did some damage. He's never reacted like that to anyone before or since. We broke it off shortly later."

"I found out a few years ago she was in the court system. Why? She tried to kill her own kid. I didn't dodge a bullet because of my cat, I dodged an artillery shell."

It's not me, it's you.

So Rude

"She didn’t hold the door open to people just meeting her at the door, would let it slam on people behind her, didn’t do the little thank you wave to other cars that let her out, didn’t say please and thank you to serving staff. She wasn’t overtly rude, she just had a bit of a me,me,me vibe."

– Hellenicparadise

Norwegian Love

"She told me she was pregnant and it was mine, 2 days after sleeping with me for the first (and only) time. Then proceeded to tell me she had a boyfriend."

"I should have twigged earlier really. She flew from Norway to sleep with me and flew back the next day."

Face Reveal

"I’d been talking to this girl in class I thought was really cool. We ended up going for a bite after class one day and she suggested we go hang out in my dorm room. Hell yeah."

"Then she took off her glasses and she looked exactly like my mom. It was so jarring I excused myself to the bathroom to regroup, but when I came back I couldn’t unsee my mom’s face on her."

"I made some lame excuse and went back alone. I felt bad about bailing on her but I also how the hell would I tell her the real reason? Either she thinks I’m a weirdo or thinks I’m saying she looks like she’s in her fifties."

Don't Speak

"My mate ghosted a girl simply because he didn't like her cadence when she spoke."

– Random-chick-98

My shallowest moment was years ago when I ghosted a hot tennis player I was dating because he had a particularly annoying gait.

Anytime we would walk around the city (in New York), he would gradually lean into me and prevent us from walking a straight path.

I thought he was deliberately trying to get close but it turned out that one of his legs was shorter than the other resulting in him taking uneven steps.

When he explained his situation, it weirded me out.

I didn't have the heart to tell him why I could no longer see him, so I just stopped responding to his incessant messages about when we were meeting next.

I remain regretful to this day about my immature behavior, and I wish him the best wherever he is.
