I don't see where your dad gets off calling you "stupid". Lets see, according to your post he has been in and out of jail and you have been a Marine. Its not easy to be a Marine. Now who really has done more with their life? So don't be down on yourself. I think I would stick with the brother who is in your corner and avoid the negative family members as much as possible. Believe me, I have difficult family members so I know where you are coming from.
