In a relationship, what is your interpretation/definition of cheating on the other half?

Doing something with someone behind your partner’s back that will compromise the relationship.

Anything that the other would consider unacceptable that was done without their knowledge.

Chatting in person or on line can be cheating if it threatens the integrity of your relationship with your SO. My notion of ‘coupleness’ is we each go our way and do our thing, but when we’ve got something to share with someone, physical affection or intimate conversation, we share it with the SO.

Doing anything that you wouldn't consider telling your other half. That includes anything hidden as well as anything involving hidden behaviour. That's my thoughts.

If you're doing anything you feel you have to hide from your partner, you're cheating.

Any kind of deceit or wrong doing

If you want to do things with others then let your partner know. Perhaps seek open relationships if you struggle to commit to one person

If he ate more than half of the fries from McDonald's if we were sharing a meal
I hate that shit

Anything sexual with someone other than your partner without their agreement.

as little as kissing is cheating, though only if it was with the sex/s they are attracted to. eg if a gay guy kisses a girl, it's not cheating in my eyes

Watching porn is a cheating

Thinking about other woman is a cheating

Eatin' aint cheatin' !! Lol
