He's gay figure it out. Even if you cheat he won't care. Don't jump into the tought of sleeping with your ex remeber he's your ex for a reason. Your overwhelmed with this news i'm sure. Just focus on your daughters and yourself for now I dont think you need anymore drama in your life right now. Be civil to your husband and figure out your future it would be best for your kids. Im sure as they grow up it will be hard enough on them having divorced parents and a dad thats gay. You will find someone that will bring you happiness just take it one day at a time. Its understandable why your so angry but if he's gay there is nothing you can do to change him. Wish you the best of luck.

  Open marriages are for freaks. Don't consider  yourself  normal. Now how about you take the high road leave and find someone  else. Now to your am I a sinner question. Yes. My brother  in law is a pastor and he will tell you we are all sinners. My brother  in law would tell you that between a prostitute  and a pastor, God look at there sin in the same way. Only one chose to ask to be forgiven. All fall short of the glory of God. No sin out ways another. Now your decisions  in life can effect greatly your outcome. And no I'm not a christian so please people don't start the Christian  bashing and go FUCK yourselves you open marriage fucks.
