personality disorder

hello,

im 16 years old and my boyfriend i think has what im hearing is called borderline personality disorder. i was wondering if i told you some of his symptoms maybe you could tell me if this is possibly what he may have, or maybe let me know of other tings his symptoms may relate to.

hes oftens throws tantrums
he always thinks everything is his fault and nothing can go his way
he always talk about wanting to end his life
he cuts and burns himself
hes drinks alot and does other drugs
has attempted to end his life
gets very angry very easily
cant control his anger (he punches and hits things including himself when mad)

those are just a few of the things i can think of off the top of my head. please get back to me ASAP. thank you.
