I don't know about you guys but it's not my 19 yr. old SS that is killing my marriage, it's his dad! He refuses to deal with his son's pot smoking and behavior. He says that he will pick his battles and that is not one of them. In the mean time I have an 18 yr. old son and a 15 yr. old daughter that live with us and ride to school in his car everyday. I have a 25 yr. old daughter that has struggled with addiction for the past 11 yrs. and it all started with smoking pot. I don't know if I can go through this again with someone elses almost grown kid.
