How do you define cheating in a relationship...

yes... of course thats a definition of cheating...

Cheating in relationship involves lying and being dishonest. As long as you are straight forward and open in a relationship then it will last longer

Ah . That is a nice topic to discuss . I would be awaiting to see the replies of our fellow members . . eh .. i would say .. Flirting would be cheating . But .. just checking out others .. err.. i don't think that would count in cheating in a relationship .. I mean .. this is my opinion .. checking out others .. would too come in cheating .. but "To appreciate beauty isn't a crime".. is it? haha .. thats an excuse i know . .

Cheating for me would require having another relationship and commitment to other person beside your present partner.

For me its define cheating!In a relationship, you need to be faithful and if you cant do it, then better be honest and be with that someone whom you are flirting or checking out!

Yes, it is. You wouldn't want your partner to do the same to you behind your back, right? If you are in a relationship, you should date exclusively. In anything you do, your partner's feelings should also be taken into consideration.
