Ill address the comment about your son wanting his Dad ......again dont worry about that and just focus on your realtionship with your son...healthy.....your son will notice your H character all on his on .....it is very hard for them to deal with their fathers actions and the more you say somehting the more they will protect.....they want their Dad to be their Dad...just like you want him to be your H....ALL i CAN SAY IS DONT DO ANYTHING TO HARM THEIR RELATIONSHIP DONT BAD MOUTH HIS DAD....IF YOU CAN DO THIS HE WILL COME TO TERMS WITH HIS DADS ACTIONS IN HIS OWN TIME....PATIENCE IS KEY...
