Thank you very much for your reply.

You're right, it does take two. He does need help. When he visited me, he mentioned that he is seeing a therapist at school. I just don't know if he realizes that he has this issue and that it is affecting all aspects of his life. I know he knows he has abandonment issues but again, not sure he knows that he acts in negative ways due to these issues. Is this something he should discuss with the family member who caused him these abandonment issues to finally deal with this problem?
