Tread, I so worry about you. I see so much anger and vindictive behavior. Not only do I worry about your harming your relationship with your child (that is his mother you are talking about), but I worry you will wake up one day and realize what you have done and feel terrible about yourself.
Please, move forward with a civil divorce and take the anger out in the gym. Leave the marriage with dignity, even if she can't. Be the honorable person if she won't. Do it for your son and do it for yourself.
