Is there ever an excuse to cheat?

Personally, I think no. If you're unhappy, then split. Simple. Never any reason to cheat.

Do you agree or is there a grey area? Have you ever cheated or been cheated on?

I do agree you shouldnt cheat if you are not happy, just say you are not happy, but dont cheat.

I have never cheated or been cheated on! I hope ?????

i have never cheated but have been cheated on, it was not a serious relationship, but still got rid of him straight away.

I always say if you aint happy then leave the relationship before bedding anyone else, I've never cheated & wouldnt, but i have met someone else whilst i was out one night which made me realise i had to leave my boyfriend asap instead of putting it off like i was. I couldnt cheat on anyone its just wrong & i wouldnt like it to happen to me. An ex purposely caused a row so i'd fall out with him, he got an ex work colleagues number & started dating her, So i thought 2 can play this game, I got a lads number whilst my ex was in the pub & we got together for 6month, when my ex found out he was soon crawling back round me. I split with the new boyf not long after as he was nice but irratatingly clingy, I got back with the ex 2mth later & always felt like he'd cheated on me as he wanted the row to go & sleep with her...several months later i dumped his ass & surprise surprise i found out i was preg 2 days later & along came josh lol. I been single ever since.
I think if a bloke cheated on me i'd sooooooooo get revenge!
