when they can't control their temper, yell curse at people.
When they don't respect my time, i.e say we are going somewhere and constantly cancel.

When it's clear they dont wanna do anything with me hehe

[c=#359E00]they are make fun/joke of everything[/c]

Taken, absolutely and if a personality doesn’t attract you that makes sense, although I have yet to find a “terrible “ personality.
I am committed for life to my best friend so not talking about a romantic relationship, but I lose interest in someone who I believe is too self absorbed.

Learning that who they really are doesn't match who they pretend to be.

Their interest in someone else

Inconsistencies.

unkindness

Yes, a bad personality does it for me. If they're rude and disrespectful to other people, it's an immediate loss of interest.

Lies put me off more than anything else. I can't stay interested if I don't feel my feelings being reciprocated either.

When they lie, or they treat waitresses badly, or they prove to be shallow, and if they're not loyal

If they're judgemental towards others
If they don't make me feel attractive or valuable

When their self centered, abusive, or have negative energy..

Stay clear of TOXIC ones

Monosyllabic conversation

If they have no sense of humour. Especially if they think they do.

Arrogance and ignorance

If they’re arrogant or just plain mean.

Poor personality- lazy or acting like a loser

When people yell at me for no reason.

Lies, negativity, nasty attitude

when they drink alcohol or are mean

When I learn our goals don't align.

Cruelty, apathy towards hurting others.

Bored

When they keep on pushing me away like i have an incurable disease

When they just stink

Bad hygene
