I don't know that it was shallow, but it sure made me uncomfortable... In my early twenties I broke up with a girl after she asked me to punch her in the face while we were having sex... I mean... I finished... but we never went out again... LOL

He almost assaulted me because I said something negative about Mother Theresa. I actually had to leave the venue because his loud over-reaction drew attention to my comment and I suddenly found myself surrounded by him and 4 other angry men with pool cues.

Open mouth chewing. It’s not a big thing I know but good etiquette makes a massive difference. I mean that’s not the sole reason but that’s probably the most petty one of the bunch.

Sweat like a pig during sex, and one of those people with the conditon where they just sweat a right ton. Same one said something really cheesy during the act. I was catching feels(hormones probab ly) before that then POOF!

I'm going through cancer treatment and he's taking a European vacation with his cousin. I'm not sure I will be seeing him when he gets back in three weeks. Lol.

30 years ago because she had a couple hairs on her chest...dumb move, nice lady

over weight

She was horrible on many levels, but when she ate, it really was a disgusting site.

She didn't like Cheap Trick.
Or the one who broke up with me because I hated the movie ET.

She had nothing to say. She would repeat the same phrase over and over, something like "That's cool". She did not have one original thought to add to the conversation.

The only thing I can think of with this question is, what do I do or have I done to make the other person stop?. That's what I need to find out and have it fixed if needed to be....

When a guy's car ran out of gas on our first date after being very late in the first place.

For me it was because he was overweight.................shallow, shallow, shallow.

Most shallow? Hard to set a "Most" standard but here is a short list: (Not sure I would qualify any of these as shallow)

#1. "I'm a Christian"

#2. "Well, I guess I'm actually married and Yea, I also have kids that I'm taking care of but my husband is in prison now so it's ok".

#3. She had the gravel voice of a chicken with the mind of child.

Darn, can't come up with anything other than "my wife would not aproved it if she find out." I was right.

I’m going to have to say that I’m probably the most shallow/worst thing that made me stop dating someone.

If they drink more than Ido.

She had two drinks before dinner...and on the second date I elected that would be the last.

I was dating a younger woman and when I got out and got dressed I found her going through my bank statements and stubs.

Ha, nice question. I woudn't have the faintest idea. Too long ago. I kept to the same for more than 40 years. But as far I remember from before, it has always been "this doesn't feel right" and never something that was said.

I'm usually not too shallow and can deal with quite alot of weirdness in a partner, but along with other logical reasons, what has made me call it quits on a girl was 1. Bad hygiene, as in she wouldn't shower after a long day and even when she did she wouldn't wash some certain parts like her hair or in her bellybutton which was smelling funky lol. 2. She blamed it on lupus but was always complaining she never felt well and refused to go do things cause random symptom caused by her hereditary lupus, a result of which she had little hard knobs in various places on her body she said were calcium deposits caused by the lupus, when I'd be touching her and ran across one, it would gross me out a little bit, but those items weren't the only reasons I left her.

Girl tried to get me to accept Jesus as my saviour.

Racism

Shrill laugh.

Shallow reasons (different people):
She did not actively participate during sex.
She talked about Dan Brown as though he was a historian.
She did not really look like her profile pic...not horribly ugly or anything, just not as expected.
The first date included her being very excited about Twilight and how she had gone to Forks when she read the first book.

None of these were really a "stop dating" thing, as we never really started dating. But shallow reasons appear early.
