I have been cheated on. Never cheated on anyone me self though. It's too simple to simply break up with someone before you go out with someone else. Why be with someone that simply does not make you happy?
I think the worst part is how "slick" the other people think they are - that you have no clue. Puh-lease! Then after the fact or after they are caught - they say, "I'm sorry - I love you - I made a mistake - etc." What a bunch of non-sensicle bollocks! If you actually 'love' someone - you do not cheat - ever.
Honestly - I think the loneliest I've ever been in me life was actually in a relasionship. I've been burned, who hasn't right? But because of the whole "Superman thing" with me - I can hostely say I have never cheated on anyone. Games are a different matter - cheat codes were made for game-lovers like me self who can't play them worth a damn.
But people - that is serious shite. I don't cheat - I don't condone cheating in any way shape or form or for any reason what so ever!
