How does Polonius treat his daughter in Act II, Scene 1 of Hamlet, and how can you tell?

Polonius does not really spend much time with Ophelia in
this scene.  However, during the time he does spend with her, he seems to be a good
father who cares about his daughter.

The main reason that I
say this is that he seems to be truly unhappy about the way that he has (he thinks)
messed up Ophelia's life.  He says that he regrets telling Ophelia to reject Hamlet.  He
says that he has hurt Ophelia by doing that.  Right at the end of the scene he blames
himself for making Hamlet crazy and (by doing that) hurting
Ophelia.
