Is there a certain type of person that you find so disgusting looking at them makes you physically nauseous?

Yes, absolutely! Honestly most men. Sorry not sorry do better!

Dumb, shallow, conceited, lazy or dull can turn anyone repugnant in short order. Unfortunately that’s most conventionally attractive people.

I’m lucky as I’m only slightly above average in looks lol.

Conversely I can fall madly in love with anyone who writes beautifully

Cruel, selfish machivellian types.
Had a boss like that.
I couldn't stand her.

She came back for a visit a few months back, and as i walked by she turned and said "Hi, how are you going?"

Once glance back at her and i just walked away. Instant repugnance. I couldn't find decent words to say to her.

Are you talking about me?

maybe but then i avoid them so i don't feel all that eh?

No
