Thought on what? Your actions, which were dumb as hell, or what you should do? As for your actions, I hope you know what you did was wrong. As for what to do now: the child she carries is yours. You have a responsibility to help care for it. You also have a responsibility to your family to spend the rest of your life making up for your betrayal. I would not expect, and neither should you, your wife to treat this woman with any kind of respect. The fact that that woman slept with you says that she does not respect your marriage or your wife. Take care of the child but have no more contact with that woman than what is necessary toward that end.
