when is it cheating?

flirting "may" lead to cheating. a simple kiss is normal.

i consider cheating if a person is not honest with me. especially in a relationship.

but honesty cannot be abused no doubt.

:)

to me there is different kinds of cheating , one emotional cheating having a close intimate relationship with someone knowingly that its more then a friendship but less then a love affair without physical affection and two physical cheating without emotional attachments the line crosser would be kiss with tongue and a emotional attachment with physical touching even holding hands falls into this category.

I call it crossing the line when it becomes sexual...I'll give credit to those who flirt or are generous with a friendly kiss but clearly end there...but sexual contact in any form crosses the line.

flirting is fine , but anything pass that is wrong for example if you're going out with this person or spending any kind of time with them is cheating.And of course touching or kissing is definitely cheating

Cheating begins when you feel you need to hide your feeling about the next person from your boyfriend/girlfriend husband/wife.

It is not cheating unless you are married.
