The fact that she was his mother might have been one of the reasons he love her so much, but it is impossible to say, because he might have loved her the same or even stronger without her being his flesh and blood.
Oedipus is shown as a good man who doesn't want to have anything to do with his destiny. He says, "Let it not happen, not that, I beg you, holy majesty of God, may I never see that day! May I disappear from among men without trace before I see such a stain of misfortune come upon me!" As in any Greek tragedy, premonitions came true and he had to suffer because of it.
