Bachelor parties are supposed to be about one last night before the ring. But when you line up recent spending and behavior estimates with infidelity reporting, the contrast gets hard to ignore, from 27% of adults admitting they cheated at least once to a 14% share naming infidelity as the reason a partner ended the relationship. The data suggests the risk is not rare, and it may start far earlier than most couples expect.
