Hope im in the right group for this, if not my apologies.  Im not sure what to do anymore.  One of my friends found themselves in a pickle so we moved in together.  Hes always been difficult but living with him has been a NIGHTMARE! His mother recently admitted that he was diagnosed with ODD as a child.  Ive looked into it, but we are both 22, theres not alot of info on ODD in adults. Any tips or helpful advice that can make our living situation more functional is greatly appreciated!
