Yes, I have noticed a difference in the two. Being played is like a game. You learn about a person. Once you find out that this person is worth time and maybe a few other advances of a relation you use this to your advantage to only be around this person for those reasons. Most of the time when a person is seeking to, "Play Around" they already have a plan established. In the end, they simply play the game until they are tired of the overall object of the game.
Cheating?! Oh, I hate it. There's nothing worse than a cheater. It starts off as the typical relationship in most cases. You Meet'em, Learn'em, Like'em, Make Plans for your future together and find out the bastard is cheating! He like you' but he like the other person too. Cheaters are usually torn between the two. Most cheaters mean to cheat but they don't mean to hurt anyone's feelings. Cheaters are usually unsure of themselves and their fututre so they are simply in a lost state of mind.
