Cheating and lying are both evading the truth. I don't see much difference. I don't want either one in my life. The Catholic church had a few things right, there are "sins" of omission and "sins" of commission. Both are not behavior I want to put up with.

Can we play outside the box? Cause neither.

If you're lying about little shit you're lying about bigger shit. Every time.

How can you separate the two, cheating is lying!

If they'll cheat 'with' you, they'll cheat 'on' you.

Personally, I find them equally repugnant.
Cheating requires lying.
Lying about "trivial things" is indicative of larger issues.

A cheater is a liar, and a liar is a cheater. And both of them are thieves, as they steal the truth and force a false reality upon those they lie to or cheat on, making the ability to make well-informed decisions concerning them impossible. Liars, cheaters, thieves... same thing.

I fail to discern the moral or exact meaning, to cheat is to lie.

There is no such thing as an “honest cheater.” Hiding what you are doing is lying. Telling someone that you love them and are in a monogamous relationship when you are unfaithful is lying If a cheater was honest about their cheating, then the partner is consenting to be in that relationship, so it’s not cheating, it’s non-monogamy.

I'll take option c). Neither

Definitely wouldn't want to be with a cheater, but why would someone lie about trivial things?

What is an example of a trivial lie you'd be okay with? That they had salmon for lunch, but said they had tuna?

That's still pretty weird.

If I had to choose... I’d stay single.

Both are bad and the same. I force myself to answer your question but my answer is always the same: none of them, thank you!

There is no such thing as a 100% honest person. If they exist they are riding unicorns.

Both bad

If they're only lying about trivial things then I would say cheating is worse. However, I'm not sure I know of a liar who can compartmentalize. For instance, our U.S. Liar-n-Chief

They are both negative reactions.An niether is better in a relationship in my opinion.

Seems they are one and the same.....attempts to get something for nothing....same as stealing...lying, cheating, or stealing....saying "only a little" doesn't change what you are. That being said...to strive for perfection is a virtue.....to expect perfection, in yourself, or others, is irrational

My ex did both. I didn't care for either.

We all lie about trivial things. I recently read where the average person lies three times in a five minute conversation. And, of course, there are always the white lies we all tell to keep out of trouble.

Aren't both the same? If you're cheating on someone, chances are you've told some sort of lie to facilitate it or cover it up. Even if somehow you've managed to cheat without explicitly lying, you're lying by omission because, in my opinion, just by being in a committed, exclusive relationship, you are tacitly saying to your partner that you are not physically or emotionally involved with anyone else.

Neither. Just walk away.

It's all prejudice....you tell me, which is better:
a. Faithful partner that will have you killed to collect insurance, keep your wealth, whatever...
b. Promiscuous partner that will be there for you when you are sick, broken, desperate, lost, etc?

They are both bad. I wouldn't want to be with or around either.

Lying and Cheating are nothing more than 2 sides of exactly the same coin.

Two sides of the same card really.
