Pretty true in general, though I don't know enough US women to compare. From what I watch/read, seems like you Americans are pretty infested with cheating. Happens here, I guess, but it doesn't seem common and it's very, very frowned on. Just hasn't been an issue I've seen among my own friends/family/acquaintances. People get together, break up, but random one night hookups and cheating seem not to be common.
