How can i be faithful to my wife?

It is natural to look at other women. It doesn't mean anything other than they are pleasing to look at. If your wife wants a "higher being" as a husband she should marry an alien, not a human man. It is not a sin, stop beating yourself up about it. And stop talking to your wife about it - tell her you have become a "higher being" and then when she isn't around, look at girls to your heart's content.
