Please can you give some quotes from Othello, displaying the love that Othello has for his wife?

You might want to start by looking in Act II scene 1, when
Othello comes back after fighting the Turks and successfully defeating them. As he
returns, he is overjoyed to be greeted by Desdemona. Note the words that he uses when he
sees her:

If
it were not to die

'Twere now to be most happy, for I
fear

My soul hath her content so
absolute

That not another comfort like to
this

Succeeds in unknown
fate.

Note the expressions of
love in his words. The sight of Desdemona after battle makes his soul so contented that
nothing else could increase that sense of contentment. Even if he were to die, he could
die in a state of perfect happiness because of his love for Desdemona and the joy that
seeing her brings to him. It is clear that these words from Othello describe a man
completely in love with his wife, and entirely devoted to her. It is worth tracing the
way that his affections change as Iago works his terrible work.
