Do you have any deal breakers that would cause you to end a relationship straight away?

For me, cheating is definitely one - I don't think I could stay with someone after that kind of breach of trust. That to me is probably the biggest one.

Any specific deal breakers for you, personally?

When one cheats in his or her relationship, it simply means that his or her partner isn't enough for the person involved and I believe cheating and infidelity is among the strongest deals that causes any kind of relationship to go beyond repair ever again because the trust in the relationship would be as good as dead and buried.

Also being a chronic liar is also another huge threat to any relationship because it kills trust and once the trust is gone in a relationship, such relationships is practical over.

That's a good one, I didn't think about that at the time of reading this thread, but thinking about it, I hate liars.

I think for me: cheating and consistent lieing.

For me, cheating is definitely one - I don't think I could stay with someone after that kind of breach of trust.

My inclination is to agree with you, but for me in the past, it's not just been any type of cheating. Four years ago, I actually discovered that my husband was cheating through messages and texting, which I guess I'd call cyber cheating. Because he agreed to see a therapist, we're still together, so I really can't say that I've been incapable of getting past any type of cheating.

That said, if he had admitted to a physical affair or if I'd found anything that would make me believe one had occurred, I would have ended our relationship immediately. And now, any type of affair or an instance of lying would be a deal breaker for me.

The idea of a physical affair seems the most painful to me. I don't know why. I've read studies that have concluded that women tend to view emotional infidelities as the worst sort of betrayal, but men seem to think it's physical. Maybe I'm just weird. 

I think the one thing that would really make me reject a relationship is the integrity of the partner. If your partner is telling lies, how could you trust anything she says? This would make the relationship a very unsustainable one and I suggest to get out of the relationship as soon as possible. You'll get yourself into a very big mess.
