The Tom Brady effect

When your significant other expects you of cheating (even though you didn't) and they are so sure of it (even with no evidence) that they take any chance they can to destroy your good name

Guy: *meets girl* *attempts to take to girl*
Girl: aren't you Richard? Didn't you date Madison?
Guy: yeah
Girl: don't talk to me she told me you cheated
Guy: I didn't do anything!
Girl: why would she say that
