What kind of conversation do Hamlet and Ophelia have in Act 3?

Hamlet's conversation with Ophelia in the third act is meanspirited. Hamlet is unjustly cruel, Ophelia is hurt and confused. The accusations and traits heaped upon Ophelia are certainly a result of his anger with his mother, but Ophelia has no idea what's going on. He tears her apart from the inside.... soiling her innocence.
