A very self-confident man

I have a wonderful life: standing next to me during difficulties, bright minded, never banal, better than me, ever. Several times I’ve been unfaithful to her but always she feigned did not see: for the family, the children, for ourselves. So, always I’m back home, because my life without her would be senseless. I know, according my disposition I know I’d never got married because I was born not to stay with only a woman. Well, now I have sex with this other: strong, sensual, explosive. But I killed her… Which one of the two? I don’t know, for I shoot closing my eyes. And now I feel too coward to open up my eyes to watch again: finding them on bed together… NO!
