I think my boyfriend has a disorder.

we have many issues with his anger.

We just took a walk in the park and I tried to speak calmly to him and he blew up he refuses to listen and acknowledge any of his issues. 

When I receive constructive criticism from him I listen and apply what I feel is needed but when I try to do the same with him he blows up and tells me what I'm saying isn't true and he is who he is and he doesn't give a fuck and if I don't like it we can break up. 

I took the advice of some ladies from here and tried to express my feelings and introduce help but it didn't go well and he walked away. 

I was calm and cool and respectful

Should I send him the article I read on narcissistic personality disorder or should I just give up because I tried talking to him already? I love him to death and although I'm pregnant whether our relationship furthers or not from this point on I can say I am truly content. I refuse to deal with it anymore and refuse to be with someone who can't acknowledge something they might not see but their partner does. so what do I do? Send him the article or not?
