I stayed with my step father a short while, he long since divorced my mom. I sure the F wasn't screwing him.
It's a relationship that it paternal in nature. Those emotions just don't evaporate because of a falling out with the mother.
Some of your posts have been entering into the Salem Witch Trials area of speculation (absolutely baseless accusations that make no sense but could get others hurt if taken seriosuly). You need to have a higher degree of skepticism and self scrutiny. You don't engage merely in gossip, but dangerous gossip that if done in real life could ruin lives, and possibly land you in court. No jury will side with you.
