I don't wish you to be UNhappy but hearing your giddiness about having an affair with your new man while dissolving your marriage and the life you loved makes me feel sick. Nice example for the kids. Jump from man to man and beb to bed, marriage is just a paper you can ignore when you so choose. No reason to say anymore, you'll justify your affair in whatever way you need so you can be okay with your actions.
Live your life while you are still living. Riding the trail less traveled.
